The Quality Imperative While quality efforts permeate Hospital for Special Surgery’s environment of care, in the operating room a surgical safety checklist forms the foundation of a new quality imperative. Before any incision is made, all members of the surgical team stop what they’re doing while critical questions are asked and answered. In the foldout that follows, we take you into the operating room of Dr. Douglas E. Padgett, Chief of the Division of Adult Reconstruction and Joint Replacement, during a total knee replacement surgery. The key to a successful

Postoperative infection is one of the most serious complications of total joint arthroplasty. Administering antibiotics prophylactically one hour before surgery significantly reduces the opportunity for the development of joint sepsis.

Before surgery, Anne Gallagher is visited by anesthesiologist Dr. Jacques T. Ya Deau, who reviews the type of anesthesia she will have. Nearly all joint replacements are conducted under regional anesthesia. This technique, pioneered at HSS, has been shown to reduce bleeding, minimize postoperative pain, shorten surgical time, and lessen the risk for surgical infection by 50 percent.

About Hospital for Special Surgery The surgical team conducts an implant time out – a protocol unique to HSS – to validate that the correct implant system is being used. The box containing the sterile implant is projected on a large screen monitor so that the information can be clearly visualized and read aloud.

Scrubbing is critical to the aseptic process to minimize patient exposure to microorganisms and the potential for surgical site infections.

The Hospital’s orthopaedic surgeons operate in a pristine environment. Each one of the 29 ORs is equipped with a laminar air flow system, which contributes to the reduction of airborne bacteria, and a Plexiglas enclosure that helps to maintain an ultra-sterile operating field.

Dr. Ya Deau and an OR nurse conduct the anesthesia time out to confirm the patient’s name, procedure, type of anesthesia, and if the patient has any allergies. They also verify that the surgical site has been signed and that blood products are available if needed.

A surgical time out is conducted before the surgeon makes the incision. At this time, a final check is conducted of the surgical site, radiological studies, instrument count, and whether antibiotics were given within the last 60 minutes, among other important components of the surgery.

a message from the surgeon-in-chief Thomas P. Sculco, MD I am pleased to bring you the 2010-2011 Annual Report of the Department of Orthopaedic Surgery. With recognition to each of our Service chiefs and their members, by all measures, the Department realized an exceptional year of accomplishments. Counted among them are the strengthening of quality initiatives within our orthopaedic services, a noteworthy surge in volume, recruitment of several new physicians, ongoing construction to accommodate our growth in patient care activities, and notable achievements in our research and academic sectors. Maintaining Clinical Excellence In 2010, our orthopaedic surgeons performed more than 25,000 surgical procedures. Inpatient admissions grew by 4.4 percent over 2009 and ambulatory surgeries increased by 3.8 percent. An emphasis on developing clinical pathways, particularly for patients undergoing hip and knee replacement surgery, has reduced length of stay enabling us to accommodate clinical volume that continues at near capacity. Of particular note is the development of a new perioperative care system for patients under the leadership of Mary K. Crow, MD, Physician-inChief and Chair of the Division of Rheumatology. Dr. Crow’s phenomenal effort in this area is enabling us to implement the new system as early as fall 2011. A major initiative, the perioperative care system will improve communication among key services involved in the treatment of surgical patients and help address quality and safety issues, from preoperative medical assessments to postoperative follow-up. A heightened attention to comorbidities that may increase operative risk, infection control, and prevention of blood clots, to name a few, will make a tremendous difference in patient outcomes. Dr. Crow has also been directing plans for the Hospital’s new Step Down Unit, which will open up recovery beds in the Post Anesthesia Care Unit (PACU) and provide a better transition of care for patients undergoing complex spinal, trauma, and arthroplasty surgery from the PACU to an inpatient nursing unit. In April 2011, Scott W. Wolfe, MD, who ably led the Hand and Upper Extremity Service, stepped down as Chief. Dr. Wolfe is succeeded by Edward A. Athanasian, MD, a member of the Service and Chair of the Resident Curriculum Committee. Dr. Wolfe is establishing a Brachial Plexus and Complex Nerve Injury Center, which will be only the third program of its kind in the country. The Center will serve patients with these catastrophic injuries and create a clinical and basic research component in collaboration with Weill Cornell Medical College. Joining Dr. Wolfe in this endeavor is Steve K. Lee, MD, who was previously Associate Chief of the Hand Surgery Division at NYU Hospital for Joint Diseases Orthopaedic Institute. In 2010, the Department of Orthopaedic Surgery welcomed Lawrence V. Gulotta, MD, who joined the Hospital’s Sports Medicine and Shoulder Service after completing his residency and a sports medicine fellowship at HSS, and an international fellowship in the management of complex shoulder reconstructions. Dr. Gulotta is organizing a clinic in this area and assisting Russell F. Warren, MD, as a member of the New York Giants medical staff. Ernest L. Sink, MD, an expert in acetabular osteotomy and open treatment of hip impingement conditions in children and adolescents, joined our Pediatric Orthopaedic Service from Denver Children’s Hospital in February 2011. Dr. Sink has also been appointed Co-Director of the Center for Hip Preservation. 2

Supporting Our Growth Over the past five years, HSS continued an upward trend in the number of patients seeking musculoskeletal care with a concurrent escalation in surgical cases. As a result, the Hospital was outgrowing its ORs, recovery rooms, and inpatient units. To ensure that our infrastructure could accommodate this growth, we began a multiphase transformation of our facilities several years ago. By 2012, we will have two additional patient care units, 35 operating rooms, 205 licensed inpatient beds, and new medical and rehabilitation facilities for pediatric patients. In 2010, we celebrated the opening of the newly constructed Center for Hip Preservation on the first floor of the Caspary Research Building, providing patients with a coordinated treatment experience offered in a single location by the Center’s multispecialty experts. This summer, we opened a new Ambulatory Care Center offsite on East 72nd Street, and we will soon open our new building on East 75th Street to house facilities for physiatry and pain management programs and for additional MRI, X-ray, and procedure rooms. This year will also see the new 7,000-squarefoot CA Technologies Rehabilitation Center at the Lerner Children’s Pavilion come to fruition. The Center will provide a spacious physical therapy gym for children and adolescents, as well as dedicated therapy rooms for working on fine motor skills and for early intervention programs. In 2012, we will open the new Lerner Children’s Pavilion, a child- and family-friendly hospital within a hospital.

Pursuing High-Level Research The Hospital’s Research Division is thriving. In 2010, the National Institutes of Health awarded our scientists multi-year grants totaling $61.5 million, and increased its funding to us by 20 percent over 2009 levels. As of December 2010, Special Surgery’s annual operating research budget was $33 million, supported by the Hospital, NIH, foundations, industry, and generous donors. I am pleased to report that the National Institute of Arthritis and Musculoskeletal and Skin Diseases awarded RO1 grants to three HSS research teams in 2010. Mathias P. Bostrom, MD, a senior clinician-scientist in the Musculoskeletal Integrity Program, will receive more than $1.5 million over four years to study mechanisms of bone integration in joint replacement surgery; Suzanne Maher, PhD, an assistant scientist in the Tissue Engineering, Rejuvenation and Repair Program, received nearly $1.5 million for a study of joint tissue substitutes to be used in a broad range of arthroplasty patients; and Timothy M. Wright, PhD, Director of the Department of Biomechanics, along with orthopaedic surgeons Robert N. Hotchkiss, MD, and Mark P. Figgie, MD, Chief of the Surgical Arthritis Service, obtained a grant of nearly $1.2 million for a three-year study aimed at understanding the biomechanical, patient, and surgical factors that affect the performance of elbow replacements. Strengthening Academic Endeavors We continue to critically review our orthopaedic residency training program and develop strategies for its enhancement, including the establishment of a web-based resident portfolio, restructuring of PGY level mentor assignments, and better integration of quality and safety issues into the curriculum. With ongoing mentorship provided by Robert G. Marx, MD, MSc, FRCSC, Chair of the Resident Research Committee, resident research productivity has progressed. In addition to implementing a grant writing workshop, we developed a mock grant review. In 2010, residents submitted 18 research grants, presented 17 resident 3

The John N. Insall Chair in Knee Surgery Established research projects – both podium and poster – at national meetings, and were awarded prizes at the national level through the Orthopaedic Research and Educational Foundation (OREF). Dennis Meredith, MD, PGY-4, and Peter Fabricant, MD, PGY-3, both were awarded OREF grants, and four former residents and fellows obtained grants from a pool of 15 grants available. PGY-5 resident Duretti Fufa, MD, received second prize for best research paper from the New York Hand Society.

In the field of orthopaedic surgery and the development of knee implants, John N. Insall, MD, is among the most famous. In the early 1970s, Dr. Insall, along with Chitranjan S. Ranawat, MD, and Peter S. Walker, PhD, developed the first total knee replacement designed at HSS. The implant was considered revolutionary, replacing for the first time the existing hinge-type implants with a more anatomically correct joint design. In 1978, Dr. Insall and Albert H. Burstein, PhD, then Director of the Hospital’s Department of Biomechanics, once again revolutionized the world of implant science, creating a knee system that provided a stable joint with a large range of motion. The total knee design they devised would bear their name, and the Insall Burstein Posterior Stabilized Knee would become one of the most successful knee replacements in the world. Dr. Insall was a fellow at HSS in 1961 and joined the Hospital in 1965. He was appointed Chief of the HSS Knee Service in 1969. He was a founding member of the national Knee Society in 1983, becoming its President in 1987. In addition to implant design, Dr. Insall was known for his groundbreaking work in ACL surgery. He trained over 200 orthopaedic residents and 100 national and international knee fellows, and authored the classic textbook in the field – Surgery of the Knee. The John N. Insall Chair in Knee Surgery is a fitting tribute to Dr. Insall, who passed away in December 2000. Made possible by the John N. Insall Foundation for Orthopaedics, the endowed chair will be held by Steven B. Haas, MD, Chief of the HSS Knee Service, and will support the Hospital’s research in knee surgery and biomechanics.

In 2011, we added a fourth hand fellow, initiated a new one-year fellowship program in the emerging growth area of hip pain and preservation, and launched an ACGME-accredited Primary Care Sports Medicine Fellowship led by James J. Kinderknecht, MD. The Musculoskeletal Radiology Fellowship Program was awarded ACGME accreditation for seven positions; the Neuromuscular Medicine Fellowship Program received ACGME accreditation for two positions per year. Two years ago, the Hospital obtained institutional accreditation status from the Accreditation Council for Continuing Medical Education, enabling us to further expand program partnerships and co-sponsorships. Collaborations for recent programming have included the American Austrian Foundation, Major League Soccer, University of Ottawa, the New York State Society of Orthopaedic Surgeons, and the International Society of Hip Arthroscopy, which held its second annual scientific meeting in Mexico in 2010 and was attended by 187 orthopaedic surgeons from around the world. In 2010, the Department launched a new professional education publication: Grand Rounds from HSS/Management of Complex Cases. We produced and distributed two issues to nearly 25,000 orthopaedic surgeons and Special Surgery alumni worldwide and paired the publication with a website component highlighting a gallery of complex case images. Edward C. Jones, MD, MA, has assumed the position of Editor. The HSS Journal: The Musculoskeletal Journal of Hospital for Special Surgery completed its fifth year of publication, reaching 19,000 health care professionals per issue. More than 100 health care professionals completed the CME process linked to accredited articles. We will be expanding the HSS Journal to three issues a year in 2011. Our close, collaborative relationships with NewYork-Presbyterian Hospital and Weill Cornell Medical College continue to produce important patient care, research, and medical education initiatives. Dr. Antonio M. Gotto, Jr., who retires this year as Dean of the Medical College, has been a great friend and supporter, and we wish him all the best in his future endeavors. Reaching Out Internationally In 2010, the third meeting of the International Society of Orthopaedic Centers (ISOC) was held in Bologna, Italy, featuring a day of scientific presentations and a half-day of meetings and work around four previously established task forces: Education/Fellowship; Outcomes/Clinical Studies/Registries; Implant Retrieval; and Information Exchange/Website. The meeting also included a new concurrent session for Chief Executive Officers of the participating institutions that focused discussions on common challenges facing leading orthopaedic centers. Results of this consortium were published in the July 2011 issue of the HSS Journal. Achievements of the 2010 meeting included

111490_L01_TXT.indd 4

9/12/11 5:33 PM

the establishment of an ISOC International Traveling Fellowship designed to provide a cross-cultural training experience, with the first selected fellow to begin in October 2011, and the launch of the ISOC website: www.isocweb.org. The next ISOC meeting is scheduled for October 2011 at Clinica Alemana in Chile. ISOC received attention in the September/October 2010 cover story of the internationally distributed professional publication Medical Meetings Magazine. Entitled “Change the World: How a Group of High-Level Orthopedists is Turning Small Meetings into Global Progress,” the article showcased the accomplishments of the Society since its inaugural meeting at HSS in 2007. Furthering our mission to promote and facilitate orthopaedic surgery education and treatment globally, we held our fourth and fifth consecutive professional education programs, with the ongoing support of the Stavros Niarchos Foundation. The four-day programs were attended by 16 orthopaedic surgeons practicing in Greece. Our 2010 program focused on “Total Hip: Replacement and Resurfacing,” which included two days of cadaveric training and observation in the operating room. In 2011, we presented a program on “Update on Total Joint Replacement of the Knee and Shoulder/Current Concepts in Sports Medicine.” During the course, participants performed total shoulder arthroplasties and knee replacements on cadaveric specimens, observed HSS surgeons performing these procedures in the OR, and attended a multidisciplinary discussion of current trends in management of sports medicine problems. In May 2011, with support from the Food and Drug Administration, the Hospital organized an international meeting of most of the joint replacement registries in the world. Held at the FDA in Silver Spring, Maryland, the meeting brought consensus on what data the registries should be collecting and began a process for developing collaborative projects that will be important to prosthesis outcomes and patient safety. The Department of Biomechanics has begun collaborating with Yan Wang, MD, President of the Chinese Orthopaedic Society, and his engineering team. The Department has recently been able to establish a communication link to receive data from CT scans of the knees of patients from China to be used in the design and sizing of implants, with the goal of producing an HSS/Sino knee system. Achieving Our Goals In 2011, HSS was again named the top hospital in the nation for orthopaedics and our Division of Rheumatology was ranked #2 by U.S.News & World Report in its “America’s Best Hospitals” issue. One reason for continued recognition by external organizations is our commitment to promoting quality and safety in the care of the musculoskeletal patient. As one of the leaders here, I continually evaluate whether the Hospital’s infrastructure is providing optimal patient safety and quality in an environment of continuous growth. Over the past several years, our quality initiatives have taken center stage in all of our strategic planning – from ways to improve patient care, to research that supports and validates our quality efforts, to education initiatives that make vital quality constructs second nature for future orthopaedic surgeons. In this report, we have dedicated a feature article to the discussion of some of our major quality initiatives. This is at the heart of our mission – to share challenges and opportunities that will benefit patients the world over.

The Importance of Patient Registries HSS has institutional patient registries in development to track patient outcomes in a number of clinical areas, including hip preservation, anterior cruciate ligament (ACL) reconstruction, and total joint replacement. The registries are used to develop scientific evidence regarding the short- and long-term benefits and risks of treatment for musculoskeletal conditions. Registry data can provide insights into patient characteristics on outcomes and establish the safety and effectiveness of new devices and new surgical and nonsurgical treatments. “While some questions can be answered with a randomized clinical trial,” says Timothy M. Wright, PhD, who oversees the Hospital’s patient registries, “a whole host of important questions remains for which you really need to know something about every patient. That’s what a registry is for. All of our institutional registries have been built around research questions and the data elements that need to be collected to answer these questions.” For example, the hip preservation registry is compiling information to determine the effectiveness of treatment for femoral acetabular impingement in improving pain and function. The ACL registry’s first question is: How will ACL reconstruction influence the development of knee arthritis? This question may take 8 to 10 years to answer. Of course, patient participation is essential to a successful registry, and at Hospital for Special Surgery, clinicians are very involved, explaining the value of registries to encourage patients to enroll. “Data from registries can be shared with patients during the clinical encounter to inform decision making and document progress, thus providing direct benefit to patients for their participation,” notes Dr. Wright.

The Quality Imperative: Methods and Metrics for Excellence in Orthopaedic Care “Our mission at Hospital for Special Surgery is to set benchmarks in standards of care and establish best practices in orthopaedic surgery that benefit the field as a whole,” says Thomas P. Sculco, MD, Surgeon-in-Chief. “A high quality, safe patient care environment overarches everything that we do. In 2010, our orthopaedic surgeons performed over 25,000 surgical procedures. The diversity of quality- and safety-related issues that arises within this tremendous volume provides a wealth of material for developing quality improvement strategies within HSS and that can be applied by institutions across the country.”

“ The diversity of quality- and safety-related issues that arises from our tremendous volume of orthopaedic procedures provides a wealth of material for developing quality improvement strategies.” Thomas P. Sculco, MD Surgeon-in-Chief

Douglas E. Padgett, MD, Chief of the Division of Adult Reconstruction and Joint Replacement, has been proactive in health care quality initiatives for more than a decade. “The reality is that medicine continues to evolve, and many of the practices in place in 2011 were not done in 2006 and in 2001,” says Dr. Padgett. “The issue about quality for me and for the people who are also passionate about it is to deliver the best care that we can in the safest manner possible. Simply put, we’re trying to make things better for our patients.” Keeping orthopaedic surgical patients safe is a multifactor endeavor, involving all members of the health care team and support from the highest levels of the institution. At HSS, quality efforts begin with the Board of Trustees, which oversees the Hospital Quality Council – the governing body responsible for directing the quality program, ensuring alignment with strategic goals, and sanctioning resources needed to meet quality objectives. This Council is chaired by Louis A. Shapiro, President and CEO, and Dr. Sculco. Steven B. Haas, MD, Chief of the Knee Service, and rheumatologist Steven K. Magid, MD, co-chair the Hospital’s Quality Coordinating Committee, which is charged with developing patient safety and performance improvement goals and projects. “Our work can range from identifying and establishing key protocols in perioperative medicine to implementing evidence-based practices in orthopaedic surgery,” says Dr. Haas. “As one example, patients coming to HSS today for surgery, compared to 10 or 20 years ago, are much sicker. So one of the challenges to our organization is how to deal with the challenges of patients with multiple comorbidities.” As the Hospital’s quality infrastructure has grown and evolved in response to internal reviews and external mandates, so have the opportunities to address quality and safety issues. “We are not only looking at traditional indicators, such as infection rates and medication reconciliation, but also how we introduce new technology and new techniques into the Hospital in a safe and effective manner,” says Dr. Padgett.

“ The issue about quality for me and for the people who are also passionate about it is to deliver the best care that we can in the safest manner possible. Simply put, we’re trying to make things better for our patients.” Douglas E. Padgett, MD

Two years ago, HSS, with its academic foundation, established the Quality Research Center to bring a scientific perspective to the quality and risk management arena. According to Dr. Magid, Chair of the Quality Research Center, potentially adverse and near-miss events provide powerful opportunities to improve patient care practice. Under Dr. Magid’s leadership, the Center has undertaken studies based on quality initiatives to demonstrate in a reproducible way how Special Surgery and other institutions can minimize risk using research principles, methodologies, and standards. Collaboration and Communication “Peer review is a mandate for all hospitals, and how that happens is done differently at different hospitals,” says Michelle Horvath, MSN, RN, CPHQ, Assistant Vice President, Quality Management. “The purpose of peer review is to constantly say, ‘There’s got to be a better way.’ At HSS, we have instituted a multispecialty Peer Review Committee, rather than a departmental-based process found at most hospitals. Our process includes representatives from orthopaedics, rheumatology/medicine, anesthesiology, neurology, radiology, nursing,

111490_L01_TXT.indd 6

9/12/11 5:33 PM

and quality departments. In this way we can review safety issues or administrative policies and procedures that may not be physician-specific, but impact the orthopaedic care provided by surgeons and other members of the health care team. This multidisciplinary approach helps to inform the process and ensures that we are looking at both the forest and the trees.” “Whether we are reviewing an individual case or looking at what may be an emerging trend within the orthopaedic surgery process, the Peer Review Committee conducts a root cause analysis,” adds Dr. Padgett. “What’s interesting is that some of the most revealing comments are made by those members who are not surgeons.” In 2010, the Hospital launched a concerted effort, led by Mary K. Crow, MD, Physician-inChief, to redesign the preoperative process. Particular attention was paid to developing risk stratification strategies so that patients can receive the appropriate preoperative evaluation and intervention, if indicated, to minimize surgical risks well ahead of the date of surgery. The most difficult cases, including those with comorbidities such as coronary artery disease, diabetes, and pulmonary hypertension, are presented to the multidisciplinary Complex Case Review Panel co-chaired by Geoffrey H. Westrich, MD, Director of Research for the Adult Reconstruction and Joint Replacement Division. “Our job on the Complex Case Review Panel is to sort out which patients may be too sick for surgery, and those who can have surgery but have concerning medical issues,” says Dr. Westrich. “We try to make sure that we have done everything we possibly can to stack the deck in their favor to achieve a favorable outcome.”

“ Our work on the Quality Coordinating Committee can range from identifying and establishing key protocols in perioperative medicine to implementing evidence-based practices in orthopaedic surgery.” Steven B. Haas, MD

Surgical Safety Measures The term “never event,” first introduced in 2001 by a former CEO of the National Quality Forum, refers to medical errors, such as wrong-site surgery, and other adverse events that should never occur. At Hospital for Special Surgery, orthopaedic surgeons have championed numerous protocols to assiduously avoid medical errors. “We were one of the first institutions in the country to implement the ‘sign your site’ prerequisite – long before The Joint Commission and New York State mandated it,” says Dr. Sculco. “We require that the attending surgeon who is going to do the operative procedure personally initial the extremity. Not only does this ensure that the surgeon takes responsibility for identifying the patient and confirming the site of surgery, but also allows the surgeon and patient to have a conversation prior to surgery, helping to alleviate any concerns the patient may have.” “There have been major cultural shifts in how we approach surgery to achieve a safe patient outcome,” says Matthew M. Roberts, MD, a foot and ankle surgeon who serves on the Hospital’s Culture of Safety Physician Advisory Group. “The first major change occurred with the signing of the patient’s extremity. That’s a very small thing that we do, but it makes a huge difference – avoiding wrong-side, wrong-site surgery – a never event.” According to Dr. Roberts, it’s important that everyone in the OR is on the same page working for safe, efficient care. Enter the Hospital’s Surgical Safety Checklist designed specifically for orthopaedic surgery. The checklist is comprised of four key areas: operating room preparation, anesthesia time out, surgical time out (before skin incision), and sign out (before the surgeon leaves the operating room). “The checklist gets everyone in the room more involved in the care of the patient,” says Robert G. Marx, MD, MSc, FRCSC, a sports medicine and shoulder surgeon who was instrumental in bringing this process to the Hospital’s surgical team. “Before each procedure, the team members introduce themselves. By doing this, everyone feels more comfortable speaking up or intervening if they identify a potential problem. The checklist also contributes to efficiency. By confirming with the operating room staff what instruments and implants are

required for the case before the start of the operation, we ensure that we won’t be delayed waiting for the missing item during surgery. Multiple published studies bear out that if all the steps of the checklist are implemented every time, you’re going to keep patients safer by decreasing complication and mortality rates.”

“ There have been major cultural shifts in how we approach surgery to achieve a safe patient outcome. A critical change occurred with the signing of the patient’s extremity. That’s a very small thing that we do, but it makes a huge difference – avoiding wrong-side, wrongsite surgery – a never event.” Matthew M. Roberts, MD

“For example, when we prepare for the case,” says Ron Perez, RN, JD, CNOR, Assistant Vice President, Perioperative Services, “we discuss issues specific to the orthopaedic subspecialty – implant options, bone allografts, type of regional anesthesia to be used, and orthopaedic equipment. Our presurgical dialogue is geared towards what we do here at HSS.” During surgery, patients are isolated from the environment as much as possible to minimize exposure to contaminants. The Hospital’s 29 ORs are equipped with a Plexiglas enclosure and a vertical laminar air flow system – a high-tech air filtration system that directs the air flow away from the operation as it simultaneously cleans and replenishes the air to maintain an ultra-sterile environment. “Unidirectional bacteria-free air flow in the ORs, combined with special hoods worn by the surgical team to control exhaled air, greatly minimizes the risk of infection,” says Barry D. Brause, MD, Chief of Infectious Disease. “The exhaled air goes into a tube that extends to the edge of the enclosure where a vacuum withdraws it from the OR. Our infection rates are very low. Indeed, we have one of the lowest infection rates in the country, and have been recognized by the State of New York for having the only infection rate statistically lower than the state average for hip replacement surgery.” The Hospital’s Infection Control Committee, co-chaired by Dr. Brause and Dr. Westrich and with over 20 members, meets monthly, covering a range of issues from how instruments and implants are sterilized to procedures for cleaning patient rooms and beds. After surgery, the Hospital follows strict postoperative protocols for preventing blood clots and urinary tract infections. Without preventive care, as many as 30 to 50 percent of patients undergoing joint replacement surgery would develop blood clots. HSS has instituted an active surveillance program to identify at-risk patients and monitor all patients for blood clots and a protocol for the use of anticoagulants and compression devices.

“ Multiple published studies bear out that if all the steps of the checklist are implemented every time, you’re going to keep patients safer by decreasing complication and mortality rates.” Robert G. Marx, MD, MSc, FRCSC

“Many of our patients need indwelling catheters until the epidural block wears off and sensation returns,” says Eileen Finerty, MS, FNP, RN, CIC, Nursing Director for Infection Control and Occupational Health Services. “To minimize the risk of urinary infection, we looked at the reasons catheters were ordered and the duration of the catheterization. Our goal was to remove catheters by post-op day two.” To accomplish this, the process for ordering and discontinuing a patient’s catheter was automated and made part of the nurse’s order set. In addition, hand-held ultrasound bladder scanners are now used to determine if the patient is making urine, thereby avoiding having to reinsert a catheter. “We’ve definitely seen our rate of UTIs come down, as well as a decrease in catheter days.” Influencing Health Care Quality As a specialty hospital that treats thousands of orthopaedic patients each year, Hospital for Special Surgery has the unique opportunity to make important inroads in quality improvement and surgical safety for this population. Information on our quality initiatives and outcomes is available on the Hospital’s quality website (www.hss.edu/quality) for review by physicians, patients, and consumers. “While tackling the quality and safety issues faced in our own hospital, we are frequently called upon to share what we learn with colleagues throughout the country,” says Dr. Sculco. “This speaks directly to our mission – to be in the vanguard of developing best practices in orthopaedic surgery and making sure that what we uncover or discover in the world of patient quality and safety contributes to good outcomes for patients not only here but elsewhere.”

Adult Reconstruction AND JOINT REPLACEMENT Division

The Adult Reconstruction and Joint Replacement Division’s 20 full-time surgeons performed approximately 8,000 surgeries in 2010, an increase of 5 percent over 2009. They provide a broad approach to arthroplasty – from surface replacement, including unicompartmental knee replacement and hip arthroscopy, to total joint replacement – both primary and revision, unilateral and bilateral. The Division’s orthopaedic surgeons are also extremely experienced in elbow replacement.

Douglas E. Padgett, MD Chief, Adult Reconstruction and Joint Replacement Division Chief, Hip Service

Over the past year, the Division has made great strides in a number of patient care, education, and research initiatives spanning all three services. In September 2010, the Hospital’s Recuperative Pain Service, which addresses pain management issues of patients in the early postoperative period, launched a pilot program with the Adult Reconstruction and Joint Replacement Division to extend treatment of non-routine pain management issues into the post-hospital rehabilitation and recovery phases. Two recuperative pain nurse practitioners, in collaboration with Dr. Vladimir Kramskiy, Director of the Hospital’s Ambulatory Recuperative Pain Medicine Program, serve as a pain management resource to patients on an outpatient basis up to eight weeks post surgery.

Mark P. Figgie, MD Chief, Surgical Arthritis Service

The Division has also implemented protocols to help reduce blood loss in total knee replacement surgery and is critically reviewing the management of blood donations in patients undergoing hip replacement surgery and their likelihood of needing a blood transfusion. These efforts have significantly reduced the need for blood donations. Under the leadership of Dr. Michael Parks, and in collaboration with the Hospital’s Patient Education Department, the Division has developed new printed and online patient education material and enhanced the preoperative class for total hip replacement (THR) and total knee replacement (TKR) patients. The patient education books are distributed in physicians’ offices, enabling patients to have standardized and comprehensive information about their surgery much earlier in the process. In 2010, the Division’s members continued to receive federal grant support for research, including a four-year research grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases for a new study to examine the mechanism of bone integration in joint arthroplasty, an NIH RO1 award to study elbow replacements, and a pilot award from the Agency of Healthcare Research and Quality to study short-term complications associated with total hip and total knee arthroplasty. The Division continues to investigate a variety of new total hip and total knee implant designs and conduct numerous outcomes studies in joint replacement. At the end of 2010, the Division began planning for the development of a Total Joint Replacement Registry, combining the strengths of current registries into one effort.

Hip Service The Hip Service has again realized growth in volume and, at the same time, has worked diligently to develop strategies that will continue to reduce length of stay and maximize the efficiency of care for patients undergoing hip surgery.

2010 Total Hip Replacements

To this end, a clinical pathways protocol has been developed for total hip replacement. The THR Rapid Recovery Pathway, which was launched in June 2010, facilitates mobility earlier in the hospital stay and has enabled more and more patients to be discharged directly to their home rather than a rehabilitation facility. The Service has taken a proactive approach in perioperative pain management to address issues of postoperative pain – a common reason for extending length of stay. The new protocol includes the use of different modalities to decrease pain, as well as nausea, so patients are able to get out of bed and begin ambulation sooner. A study by members of the Hip Service showed that generally healthy patients who undergo total hip replacement can be fast tracked to be discharged safely in two days compared with the standard three to six days. This may ultimately help reduce hospital-acquired infections and hospital costs, and improve patient satisfaction. Patients in the study who were released within two days did not have an increase in complications, readmissions, or reoperations. Another study by the Service looked at preventing postsurgical blood clots after hip replacement surgery and found that a compression device works as well as medication, is as useful as blood thinners, and is superior in safety. The results have the potential to change the paradigm as to how to prevent blood clots after hip replacement.

Knee Service The Knee Service continues to move the field of knee replacement forward in design development of implants and biomaterials, with a focus on creating prosthetic knee joints that will function at higher levels, last longer, and enable patients to recover faster. Seeing many more patients in their late 40s and 50s who want to return to a lifestyle of high-energy activities, the Knee Service is looking at implant systems that take into account the performance expectations of younger patients. These implant systems include newer cross-linked polyethylene and lower contact stresses intended to preserve the wear of the polyethylene component, allowing the polyethylene to endure for a longer period, thereby providing a more resilient knee implant for the active adult. Additionally, the Knee Service has begun collecting performance data relevant to the younger patient, including information related to skiing, golf, racquet sports, cross-country running, biking, and all types of exercise. At the same time, Service members continue to explore less-invasive surgical approaches using modern instrumentation and partial knee replacement, incorporating the use of computer-assisted surgery in patients who undergo partial knee replacement for more precise placement of the implants. Additionally, helping to advance minimally invasive knee replacement surgery, our orthopaedic surgeons are using MRI to develop preoperative plans. By first performing a virtual operation on the computer, they can then design custom-made instruments specific to the case, reducing the number of instruments typically needed in this type of surgery. The Knee Service is committed to providing perioperative pain management as a priority for patients undergoing total knee replacement. Adjuvant therapies, such as supplemental blocks injected at the time of surgery, have been shown to decrease postoperative pain.

Surgical Arthritis Service An important initiative of the Surgical Arthritis Service is focused on patients under the age of 35 who had joint replacements. Service members are looking at what prompted the joint replacement, how the joint replacement is affecting their activity, and implant survivorship. Plans are to develop this effort into a nationwide multicenter study, which is expected to provide the largest and longest follow-up on patients with juvenile inflammatory arthritis. Service members have long been involved in research to determine why elbow replacements fail and what can be done to increase their longevity – different designs, improved fixation methods, and better options for revision surgeries. By studying failed elbow implants, they have identified mechanisms of failure and are designing an elbow replacement to uniquely address what was learned. Service members also incorporate 3-D modeling preoperatively to be able to precisely determine any defects or other challenges presented by a joint replacement case, thereby providing the surgeon with a better ability to plan the surgery and decide if a custom implant is required. This is particularly valuable for patients with juvenile inflammatory arthritis, hemophilia, and skeletal dysplasia, which can affect growing bone and cause major deformities within the joint.

FOOT AND ANKLE SERVICE

The Foot and Ankle Service, with eight full-time orthopaedic surgeons, is the largest of its kind in the country. Members of the Service continue to refine techniques in the reconstruction of foot and ankle deformities. In addition, foot and ankle problems in sports are a major focus of the Service, with several members consulting with professional sports teams, including the New Jersey Nets, New York Knicks, New York Giants, New York Mets, and New York Red Bulls, as well as the American Ballet Theatre. The Service has particular expertise in the treatment of Lisfranc injuries, which, while uncommon, can be highly debilitating for athletes who depend on their lower extremities for performance.

The Service has made great progress in pain control following foot and ankle surgery. Working collaboratively with the Department of Anesthesiology, the Service has developed a postoperative pain protocol using popliteal fossa nerve blockade along with various combinations of pain medications. With this, patients have been able to leave the Hospital with less discomfort. Anesthesiologists are currently tracking a cohort of patients using these different medication combinations to determine the duration of the analgesia after the nerve block. In addition, the Service is involved in a pivotal prospective, randomized, controlled, multicenter clinical trial to evaluate the safety and effectiveness of GEMOSI compared to autologous bone graft as a bone regeneration device in foot and ankle fusions. The Foot and Ankle Fellowship Program includes three accredited positions, providing clinical knowledge and research skills in all aspects of foot and ankle care, including total ankle replacement, endoscopic and minimally invasive techniques of the foot and ankle, and adult flatfoot deformity. Fellows participate in ongoing clinical and basic science research programs and academic conferences, supervise patient care, and gain an in-depth surgical experience. Plans are now in development to further the training experience in complex pediatric reconstructive procedures and acute foot and ankle trauma, as well as to provide fellows with protected research time and related support. The Foot and Ankle Service maintains a productive research program. Among the Service’s multiple ongoing research endeavors are the evaluation of radiographic parameters of successful versus unsuccessful flatfoot reconstruction; investigation of syndesmotic and lateral ankle injuries in the National Football League; and the use of platelet rich plasma on Achilles tendonitis. In 2010, the Foot and Ankle Registry, supported by the Susan and Elihu Rose Foundation, continued to expand. The Service-wide registry has enrolled over 29,550 patients and, to date, there are 11 research studies underway using data collected by the registry.

HAND AND UPPER EXTREMITY SERVICE

The Hand and Upper Extremity Service provides subspecialty expertise in tumor, congenital, microsurgery, elbow reconstruction, neuromuscular disease, sports injuries, minimally invasive surgery, and microneural reconstruction. It also directs the hand surgical services at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, Memorial Sloan-Kettering Cancer Center, and the James J. Peters Veterans Administration Medical Center in the Bronx. In 2011, the Service recruited a hand and wrist surgeon with peripheral nerve and microsurgery expertise, bringing the total faculty complement to eight orthopaedic surgeons. The Service also developed plans for the Center for Brachial Plexus and Complex Nerve Injury, scheduled to launch in Fall 2011. The new multidisciplinary Center – the first of its kind in New York – will offer neurodiagnostic and intraoperative testing in collaboration with the Hospital’s Neurology and Physiatry Departments. The Center will also build on the Service’s existing brachial plexus registry, with ongoing data collection and research to facilitate assessment of outcomes and long-term improvement of care for these patients. During the past year, the Service’s fellowship program was approved to train a fourth ACGME-accredited fellow, given the high case volume and outstanding educational experience provided. The Hand Surgery Fellowship is particularly sought after due to the breadth and depth of hand procedures performed at HSS and the opportunities for fellows to train in specialty niche areas. The Service continued its New York City exchange fellowship rotation with Bellevue Hospital, which provides a month-long microsurgical and replantation training experience. The Service’s resident and medical student rotations provide an intense immersion in hand surgery. Two residents – a PGY-3 and PGY-4 – complete two six-week rotations on the Service, which has implemented a mentorship approach to facilitate learning. In 2010, a trial Senior Resident Fellowship was initiated in which PGY-4 and PGY-5 residents assume complete responsibility for one of four subspecialty areas. End-rotation evaluations demonstrated that the Senior Resident Fellowship affords a rewarding and productive learning experience. The Hand and Upper Extremity Service has more than $3 million of local, regional, and national competitive grant funding for its research activities. The Service successfully completed three randomized trials of pharmacologic agents for distal radial fracture healing and Dupuytren’s disease. The Service continues to grow well-established patient registries in basal joint, distal radius, carpal tunnel, neoplasia, pediatrics, brachial plexus, and the elbow. In 2010, the Service engaged in an extensive analysis of data looking at the treatment of patients with soft tissue sarcomas of the hand, particularly the oncologic outcomes and complications associated with the use of radiation and the utility of MRI as a predictive tool of residual disease.

LIMB LENGTHENING AND COMPLEX RECONSTRUCTION SERVICE The Limb Lengthening and Complex Reconstruction Service is among the most comprehensive limb lengthening programs in the world today. The Service continues to grow substantially in patient volume and research activities. In 2010, the Service further developed approaches and techniques incorporating new surgical options, improved tools, and bone healing enhancement, providing treatment opportunities for patients who have no other alternatives. Vitamin D levels of 65 to 70 percent of the Service’s patients are considered low enough to delay bone healing. To that end, Service members developed an aggressive protocol in collaboration with the Hospital’s Metabolic Bone Disease Service to assess Vitamin D levels preoperatively and created an algorithm for treatment.

Making an assessment of when bone is healed is a challenging and largely subjective process. In concert with the Department of Radiology and Imaging, the Service has initiated an investigation to validate an objective tool to determine when bone is healed. The approach, which involves the use of PACS (Picture Archiving and Communication System) to study pixel density that appears in newly lengthened bone, may well contribute to other areas of orthopaedics beyond limb lengthening and reconstruction, especially in the treatment of fractures. The Service’s education program is focused predominantly on two clinical fellows who receive intensive exposure to surgical, inpatient, and outpatient clinical care. The Limb Lengthening Fellowship provides in-depth experience in the management of patients with congenital, developmental, and post-traumatic limb deformity and leg length discrepancy. Emphasis is placed on evaluation and both nonoperative and operative management of these problems. Since 2008, the Service has offered a clinical elective to visiting medical students and residents with great success. Students participate in teaching conferences, journal clubs, and case reviews. Research initiatives in 2010 included three new prospective randomized clinical trials: evaluating the effect of platelet rich plasma therapy on bone healing during limb lengthening; a comparative study of two systems for autologous bone marrow harvesting; and comparing the effect of two protocols of antibiotic prophylaxis on pin tract infections. Studies continue to evaluate a number of limb lengthening techniques, including the Ilizarov method in the reconstruction of bone tumors, as well as in complex ankle fusion. In addition, Service members are involved in three prospective gait studies evaluating the effect of proximal tibial osteotomy in adults and children and one comparing the functional gait of limb salvage patients to amputation patients. The Service maintains a strong presence in the Limb Lengthening and Reconstruction Society, and at its 2011 annual meeting, Service members presented 10 of the meeting’s 50 abstracts – the single largest institutional representation at the meeting.

METABOLIC BONE DISEASE/ MUSCULOSKELETAL ONCOLOGY service The Metabolic Bone Disease/Musculoskeletal Oncology Service continues to confront the challenges of bone development and fracture healing, emphasizing strategies that guide the use of agents in a particular clinical presentation. The Service is now delving aggressively into the study of anabolic agents – which actually make bone – including piloting their use in spine surgery and to enhance healing in fragility fractures. The Service is also studying the use of anabolic agents to rapidly speed the healing of stress fractures in athletes and looking at low Vitamin D levels in members of professional sports teams. In 2010, a study by HSS investigators showed that a professional team’s performance was directly related to its members’ Vitamin D levels. Players with lower levels were sub-performers in terms of speed and weightlifting and also had more injuries. The implication is that Vitamin D may play a critical role in the performance of an athlete.

Joseph M. Lane, MD Chief

In addition, studies point to the benefits of raising levels of Vitamin D – essential for bone healing and muscle function – prior to an orthopaedic procedure. Members of the Service have found that nearly half of patients undergoing surgery have a Vitamin D deficiency, which can impair recovery, and have now implemented a protocol to improve Vitamin D levels before surgery for affected patients. In patients with slow healing bone, the Service has begun using an autologous technique prior to surgery in which bone marrow stem cells concentrated with bone morphogenetic protein are injected at the fracture site. Researchers have found that this percutaneous technique has led to successful healing for delayed and nonunion fractures in nearly 75 percent of patients.

Based on the work previously conducted by the Metabolic Bone Disease Service that demonstrated the need for a “pause” from osteoporosis drugs, the Service has established a protocol that individualizes drug treatment based on specific patient characteristics, including bone markers and fracture history, with dosing and duration of treatment dependent on patient responses. As a result, complications – including atypical fractures and osteonecrosis of the jaw – associated with long-term use of osteoporosis drugs have decreased. The Service has been one of the nation’s strongest advocates recommending that patients take a pause in their osteoporosis medication usage after five years, a protocol that has been endorsed by the FDA and adopted by physicians throughout the county. Research activities include the Seymour Cohn Metabolic Bone Registry, which collects and analyzes patient data sets to identify methods to prevent and repair fragility fractures that result from osteoporosis and other metabolic bone disorders, and the Bone Mineral Density Core, which focuses on the repair and regeneration of bone and cartilage and other soft tissues, which is critical to the understanding of bone diseases.

orthopaedic trauma service

The Orthopaedic Trauma Service has continued to focus efforts on understanding bone fixation in fractures in the elderly to develop better techniques to stabilize osteoporotic bones. The challenge is to address bone quality in the setting of multiple comorbidities; associated risks, including infection, pulmonary embolism, pneumonia, and urinary tract infections; and other issues such as lifestyle and nutrition that can impact treatment. The Service applies a multisystem evaluation, drawing on medical, geriatric, and metabolic bone disease expertise, and pain management and physical therapy, to help heal and strengthen bones and improve outcomes. The Medicine Orthopaedic Trauma Service (MOTS), established in 2008 in collaboration with NewYork-Presbyterian/Weill Cornell, is thriving. The dedicated service manages the care of elderly patients with multiple orthopaedic and medical problems. Staffed full time by a member of the geriatric team at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, MOTS has made a major difference in the management of older patients who arrive in the Emergency Department with hip fractures. Through this program, the Service has been able to minimize the risk of complications and maximize medical status to prepare patients for surgery, rehabilitation, and recovery.

David L. Helfet, MD Chief David E. Asprinio, MD Gregory S. DiFelice, MD Andrew Grose, MD Joseph M. Lane, MD Dean G. Lorich, MD John P. Lyden, MD

The Service also actively participates in the Hospital’s Center for Hip Preservation, addressing traumatic hip injuries in younger patients, with a goal of preserving the hip in order to avoid early hip replacement.

The research component of the Orthopaedic Trauma Service includes a large database of complicated and unusual cases that forms the basis of important basic science and clinical research endeavors. A fragile bone registry collects data on patients with osteopenia, osteoporosis, or a history of low energy fracture, facilitating investigations in developing a better understanding of the clinical features, pathobiology, and genetic links associated with fragile bones. The Service is conducting multiple vascularity studies, particularly in the shoulder, hip, ankle, and knee, to preserve the blood supply to certain problem bones and fractures and tailor surgery accordingly to avoid complication. Ongoing studies include an assessment of the effect of patellar fracture on the vascularity of the patella using gadolinium in enhanced magnetic resonance imaging and surgical implications of anterior versus posterior surgical hip dislocation. Fellowship training takes place at Hospital for Special Surgery and NewYorkPresbyterian/Weill Cornell. Additionally, the fellows rotate for four months with Drs. David Asprinio and Andrew Grose at Westchester Medical Center, which has one of the busiest Level 1 Trauma Centers in New York State. Through the HSS orthopaedic trauma referral program, fellows gain extensive experience in management of more complicated polytrauma or periarticular orthopaedic trauma.

PEDIATRIC ORTHOPAEDIC SERVICE

The Pediatric Orthopaedic Service realized a number of important achievements in 2010-2011. The Service expanded with the appointment of Dr. Ernest L. Sink, a pediatric orthopaedic surgeon who has specialty expertise in adolescent and young adult hip reconstruction, with particular emphasis on periacetabular osteotomies and surgical dislocation. Surgical dislocation involves recontouring the hip to alleviate stress on the cartilage and prevent the development of degenerative arthritis or the need for pelvic osteotomies. The goal of this hip preservation technique is to allow the patient’s native hip to endure indefinitely. The vast majority of patients presents in their late teens and early twenties and have developed either impingement or hip dysplasia once skeletally mature. This fall, the Service welcomes its ninth pediatric orthopaedic surgeon who has a particular interest in outcomes research. The pediatric orthopaedists each focus their practice in a specific subspecialty area, including cerebral palsy and neuromuscular problems, pediatric foot, pediatric sports medicine, spinal deformity, hip problems, and trauma. Their expertise is complemented by pediatric nurses, nurse practitioners, physician assistants, rehabilitation therapists, and other allied health professionals highly trained in orthopaedics. The continued growth of the Service over the past five years and the subsequent growth in patient volume will soon be accommodated with the opening of the Hospital’s new Lerner Children’s Pavilion. In 2010, significant progress was made on construction of this “hospital within a hospital.” In fall 2011, the new CA Technologies Pediatric Rehabilitation Center is scheduled to open, and in mid-2012, the Lerner Children’s Pavilion will make its debut, bringing together all of the Hospital’s pediatric clinical and surgical services in a family-centered environment. Patient education remains an important focus of the Pediatric Orthopaedic Service, which continues to expand its series of condition-specific guides to provide pediatric patients and families with in-depth information about diagnosis, treatment, and recovery. Most recently, the Service published guides on pediatric scoliosis surgery, pediatric external fixators, and varus rotational osteotomy, and produced a 12-minute video on what to expect before, during, and after surgery. The Service recently reported on a 10-year study of teenagers who underwent fusion for adolescent idiopathic scoliosis using the newer generation of spine implants. The study showed that the surgery appears to spare junctional disc degeneration and allows patients to have a relatively normal pain-free lifestyle. Registries in osteochondritis dissecans, pediatric fractures, and patella subluxation continue to grow, and there are currently 10 active research projects that address scoliosis surgery on the adolescent athlete, methods for assessing bone age, and change of ankle kinetics and kinematics following proximal femoral varus osteotomy.

SCOLIOSIS SERVICE

Developing and refining approaches in complex spine surgery continues to be a focus of the Scoliosis Service. For the past few years, the Service has been employing transcranial magnetic motor-evoked potentials and spinal cord interoperative monitoring during surgery, eliminating the wake-up test and alerting surgeons to warning signals of possible spinal cord injury. The use of these monitoring techniques has tremendously reduced spinal cord injury during surgery to virtually none.

The Service further developed the use of minimally invasive surgery for adult deformities. Many of these surgeries involve long fusions, requiring welding of the vertebrae and instrumentation over many segments of the spine. In combined anterior and posterior surgeries, surgeons are now able to approach the anterior portion of the spine with smaller incisions. The Service’s surgeons also use transsacral interbody fusion to stabilize the base of the spine without going through the abdomen. In this procedure, the front part of the lumbar spine is fused from below. These minimally invasive procedures have reduced morbidity and length of stay and improved patient outcomes. The Service is also using applied biologics, such as bone mineralized protein (BMP), to facilitate spinal fusion and avoid having to use bone from the rib cage, which can bring complications of chronic pain and difficulty breathing. The use of biologics has greatly increased the Service’s fusion rates. In 2011, the Service inaugurated the John R. Cobb, MD, Fellowship, bringing on its first fellow for comprehensive training in the management of all deformities and pathologies of the cervicothoraco-lumbosacral spine in pediatric and adult patients. The fellowship focuses predominantly on spinal deformity and is geared to the orthopaedic surgeon who is interested in a career in scoliosis and spinal deformity surgery. The rationale for this unique one-year fellowship dedicated primarily to spinal deformity grew out of the need to offer extended training in a field that has become increasingly complex in terms of instrumentation and newer surgical techniques available. Several years ago, the Service initiated a Scoliosis Registry, which to date has enrolled more than 2,000 patients. This robust registry has enabled the Service to conduct a number of clinical studies – many now completed, published, and presented at international meetings. These include a comparison of selective versus non-selective thoracic fusions; complications and revision rates for long fusions terminating at l5 versus the sacrum in adult spine deformity; and surgical outcomes review of adult idiopathic scoliosis. Several members of the Service also participate in multicenter studies, including the Complex Spine Study Group, the International Spine Study Group, and the Spinal Deformities Study Group.

SPINE SERVICE

With a goal to advance patient care, develop an infrastructure for continued clinical and basic science research, and improve the education of residents and fellows, the Spine Service continued to focus on implementation of the multidisciplinary Spine Care Institute and the Integrated Spine Research Program in 2010. The surgeon-led Spine Care Institute is a Center of Excellence for both operative and nonoperative spine care, facilitating a seamless continuum among the Hospital’s multiple disciplines and resources that provide treatment for patients with spinal disorders. In 2010, the Service held four multidisciplinary case review and educational conferences for all members of the Institute, and launched a distinct website within the HSS parent website to enhance patient access to information, including videos that describe various procedures. In addition, we are exploring the role of the Hospital’s Integrative Care Center as a key partner with the Spine Care Institute to further enhance nonoperative care for spine patients. In concert with the Metabolic Bone Disease Service, a clinical research program has been established to further elucidate the relationship between metabolic bone disease and spinal disorders, especially the effect on bone fusion. The new Integrated Spine Research Program provides an infrastructure that continues to promote both basic science and clinical research. During the past several years, the Spine Service has been involved in a number of prospective randomized clinical trials, including the NIH-funded Spine Patient Outcome Research Trial (SPORT). SPORT has resulted in articles in The New England Journal of Medicine, Journal of the American Medical Association, and Spine. Other prospective trials have included non-fusion technologies in lumbar and cervical total disc replacement arthroplasty. HSS was a main site for the IDE clinical trial for ProDisc-L for the treatment of two-level degenerative disc disease, the findings of which were published in the Journal of Bone & Joint Surgery (Am). The Service is also refining its clinical outcome measures, combining the SF-12 health survey, Oswestry Disability Index (ODI), and the Neck Disability Index (NDI) in a scale that better describes patient postoperative function for outcome analysis.

The Spine Service has continued basic science research in orthobiologics in bone healing using animal fusion models. Members have studied the efficacy of bone morphogenetic proteins (BMP), demineralized bone matrices (DBM), and beta-tricalcium phosphates (beta-TCP ceramics), and investigated a new surface coating for metallic implants. In 2010, the clinical fellowship was further strengthened with an emphasis on research. Each clinical fellow spends one day a week devoted to research, which has resulted in a number of projects accepted for presentation at national and international society meetings.

SPORTS MEDICINE AND SHOULDER SERVICE

David W. Altchek, MD Scott A. Rodeo, MD Co-Chiefs

With 25 orthopaedic surgeons and five primary care sports medicine physicians, the Sports Medicine and Shoulder Service continues to capitalize on its size, depth, and range of expertise.

Answorth A. Allen, MD Struan H. Coleman, MD, PhD Frank A. Cordasco, MD, MS Edward V. Craig, MD, MPH David M. Dines, MD Joshua S. Dines, MD Stephen Fealy, MD Lawrence V. Gulotta, MD Jo A.

Ranawat, MD Howard A. Rose, MD Beth E. Shubin Stein, MD Sabrina M. Strickland, MD Russell F. Warren, MD Thomas L. Wickiewicz, MD Riley J. Williams, III, MD

Service members provide medical coverage to professional teams and organizations, including the New York Knicks, New York Mets, New York Giants, Nets Basketball, New York Liberty, New York Red Bulls, U.S. National Rowing Team, and the U.S.A. Swimming National Team, as well as many college and high school athletic programs. For all levels of athletes, the Service is focused on developing and refining techniques for more precise diagnosis of injuries and better defined, less-traumatic nonoperative or operative treatments that can return players to their previous skill level quickly and safely.

Innovators in the field of sports medicine, the Service’s physicians continue to be at the forefront of elbow reconstruction for injuries in the overhead athlete and repair of the anterior cruciate ligament. They also specialize in challenging cartilage problems that often involve complex osteotomies of the tibia or the femur and new and constantly changing cartilage replacement techniques. Major shoulder surgery – both primary and revision shoulder arthroplasty – is also a key area of focus. Surgeons incorporate CT scans with 3-D reconstruction to evaluate boney anatomy, particularly around the shoulder and the hip, which ultimately guides therapeutic intervention. The Service is expanding its Primary Care Sports Medicine Program under the direction of Dr. Brian C. Halpern with the recent addition of two new physicians in 2011: Dr. James J. Kinderknecht and Dr. Marci Anne Goolsby. Research remains a top priority of the Service’s mission, with a commitment to collaborative group efforts in both basic and clinical research. The Service welcomed Sherrie Vassallo as the Director of Clinical Research to manage the many research activities of the group. Primary research efforts focus on soft tissue and cartilage reconstruction of joints and their clinical application to the active individual. The Service is pursuing in-depth studies in knee ligament stability, shoulder stability, rotator cuff tendon healing, and articular cartilage repair. A major component of the program includes the development of computerized research registries that track outcomes of patients undergoing surgery for ACL reconstruction, rotator cuff repair, shoulder stabilization surgery, and cartilage defects. The Service has created an articular cartilage repair registry, and great progress was made in the past year in the redesign of its ACL Registry. To date, 670 patients are enrolled in this registry. In 2011, the Service assumes stewardship of the total

shoulder registry created by the Center for Education and Research on Therapeutics (CERT). The Service continues to engage in a broad span of basic science research initiatives. Working with the Biomechanics Department has allowed for ongoing studies of knee and shoulder mechanics using a state-of-the-art robotic testing system. In conjunction with the Motion Analysis Laboratory, muscle function in patients with rotator cuff disease is being examined. The Service has established an ongoing collaboration with the Laboratory for Soft Tissue Research, Scott A. Rodeo, MD, and David W. Altchek, MD where studies include assessing feasibility of a non-biodegradable scaffold for treatment of osteochondral defects in a rabbit model; studies of the effect of mechanical loading on ligament fibroblasts; and evaluation of the effect of strain on ligament graft healing in an animal model. Researchers are also conducting basic laboratory studies in tendon and ligament biology, looking at cell2010 Patient Care Volume based approaches to tissue healing with a goal to bring these to the clinical trials arena. Translational research is also underway using models of Vitamin D deficient rodents to evaluate the histology and mechanical properties of rotator cuff repairs. If rotator cuff healing is superior in the Vitamin D repletion group, this data has the potential to be used in humans. Trials will soon begin in patients for rotator cuff repair using bone marrow-derived cells to determine if they augment healing. Several prospective projects have recently been completed on rotator cuff repair and arthroscopic shoulder instability surgery, with current projects investigating shoulder surgery focusing on anterior instability in adolescents.

The Sports Medicine Fellowship Program has seven accredited positions, an additional international fellow, and a two-year fellowship position that permits a dedicated research year. The Service established a fellowship program in primary care sports medicine, welcoming its first fellow in July 2011. In 2010, the Service established small teaching groups – or pods – comprised of three to four orthopaedic surgeons, as well as a primary care physician, physical therapist, and physician assistant, based on similar interests and expertise. The goal is to enhance fellowship and residency training. This approach has been well received and can serve as a template to other large services at HSS.

 Launched a Primary Care Sports Medicine Fellowship beginning in July 2011

 Furthered a relationship with the New York Road Runners Club, holding a series of multidisciplinary education

DEPARTMENT OF BIOMECHANICS

The Department of Biomechanics remains a vital link between orthopaedic surgeons at Hospital for Special Surgery and translational research aimed at providing the best care to their patients. Collaborative research among the engineers in the Department and the orthopaedic staff spans from developing new treatments through to postoperative assessment of treatment efficacy. The past year was no exception in this ongoing process of continual improvement.

For example, research with the Sports Medicine and Shoulder Service has led to the development of a class of novel biomaterials for use in cartilage repair, meniscal replacement, and ligament reconstruction. By applying lessons learned by HSS surgeons and engineers in developing total joint replacements, the design of these materials centers on their ability to transfer the large loads that patients place across their joints during daily activities. Thus, treatments employing these new materials will not only relieve pain, but also restore function to the diseased or injured joint. For more than 30 years, the Department of Biomechanics has been analyzing joint replacement implants retrieved from patients, amassing the largest collection in the world and providing surgeons and biomechanical engineers the rare opportunity to examine how the implants functioned while implanted. Such analysis suggests ways of improving performance through new designs, while also affording the means of comparing the effectiveness of existing designs. As one example, progress continued over the past year in combining observations of failed elbow replacements with computational stress analysis to understand why these implants undergo a higher rate of mechanical failure than their counterparts in the hip and knee. The results have fostered innovative new design concepts that are currently undergoing rigorous testing before applying them in the clinical setting. Medical students, biomechanics graduate students, orthopaedic residents, and postdoctoral fellows are an integral part of the research and development projects in the Department. By effectively engaging these trainees in the research environment, they experience firsthand clinical problems that require engineering solutions while, at the same time, they benefit from the synergy created by integrating students from multiple disciplines. A cornerstone of these efforts is the Hospital’s Ruth L. Kirschstein National Research Service Award from the National Institutes of Health. With more than 25 years of continuous funding, the award has enabled the creation of a Musculoskeletal Training Program that supports two postdoctoral fellows and one predoctoral student. These students contribute greatly to all orthopaedic services at HSS. We continued to emphasize the recruitment of women and minority students into bioengineering and orthopaedics, including participation in the Perry Outreach Program and a Luce Foundation grant for fellowships for women in engineering.
