Diagnosis: Pes Anserine Tendinitis Discussion Pes anserinus, which is Latin for “goose’s foot”, describes the webbed footlike configuration of the joint distal insertion of the sartorius, gracilis and semitendinosus tendons onto the proximal aspect of the anteromedial tibia. Pes anserine bursitis/tendinitis typically affects older individuals with arthritis as a consequence of constant friction with underlying osteophytes; however, young runners may suffer from this condition as well due to repeated valgus stress and recurrent microtrauma. The clinical presentation consists of medial knee pain and swelling that is exacerbated by climbing or going down stairs. The treatment includes rest, NSAIDS, physical therapy, and/or therapeutic bursal injection with anesthetic and/or cortisone.
