Knee Surgery

by Steven Paull

So I now find myself in the position where I am unable to walk due to the pain and now having to use a cane to walk.

My doctor has referred me to a specialist to prepare for an operation to help me. I did a little research through Dr Google and talking to some friends who have had the procedure.

When a knee replacement, also known as knee arthroplasty, is performed, the damaged or diseased parts of the knee joint are replaced with artificial components. The procedure is typically recommended for individuals who have severe knee pain and limited mobility due to conditions such as osteoarthritis, rheumatoid arthritis, or knee injury.

Here is a general overview of what happens during a knee replacement procedure:

Anaesthesia: The patient is administered anaesthesia, which can be either general anaesthesia (puts the patient to sleep) or regional anaesthesia (numbs the lower body).

Incision: The surgeon makes an incision in the front of the knee to access the joint.

Reshaping the Bones: The damaged surfaces of the thigh bone (femur) and shin bone (tibia) are precisely cut and reshaped using surgical instruments to accommodate the artificial components.

Placement of Artificial Components: The artificial components are inserted into the prepared bone surfaces. The most common type of knee replacement involves three components: a metal component for the end of the thigh bone, a metal and plastic component for the top of the shin bone, and a plastic spacer to provide a smooth gliding surface between the metal components.

Closure: The incision is closed using stitches or staples, and a sterile dressing is applied.

Postoperative Care: After the surgery, the patient is taken to a recovery area and closely monitored. Pain management, physical therapy, and exercises to regain strength and range of motion are typically part of the postoperative care plan.

The specific details of the surgery can vary depending on factors such as the patient's condition, the surgeon's technique, and the type of knee replacement being performed (e.g., total knee replacement, partial knee replacement). It's important to consult with a qualified orthopaedic surgeon for personalised information and guidance regarding knee replacement surgery.

4 Signs That You May Need A Knee Replacement

Swollen Knees: Your knees are always swollen or puffy, despite taking antiinflammatories, attending physical therapy, and/or icing your knee.

Deformed Knees: Severe arthritis and cartilage deterioration can lead to your knees appearing bowed or “Knock-Kneed”.

Limited Range of Motion: You are no longer able to straighten your leg or notice distinct changes in your walk, such as a persistent limp or inability to walk up stairs.

Constant or severe pain: When resting.
