You may expect something called the goose’s foot to be in or near the foot itself, except it is actually located near the knee. Instead of describing a location, this rather odd anatomical term refers to the shape of the insertion of three muscle tendons that blend together to make up the pes anserinus (Latin for goose’s foot). These muscle tendons, in combination with an underlying bursa, can be the cause of pain just distal to the knee joint and medial to the tibial tuberosity. This bursitis related pain should be differentiated from other causes of knee pain and treatment should include measures to reduce inflammation of the bursa.
