Goosefoot bursitis, also known as medial tibial condylitis, occurs in the medial condyle of the tibia just below the inside of the knee joint. Goosefoot is formed by the convergence of the tendons of the thin femoral, suture, and semitendinosus muscles of the thigh, and is named for its shape, which resembles that of a goose’s foot. The bursa of the goosefoot, on the other hand, is the bursa between the tendon of the goosefoot and the medial collateral ligament of the tibia. Goosefoot bursitis is an aseptic inflammation of the muscles and tendons in this area due to injury caused by repetitive stimulation of the knee joint through flexion and extension activities. It is common in athletes, fitness enthusiasts who have a high level of physical activity, or elderly people who lack exercise. The common symptoms are pain and swelling on the inner side of the knee joint, increased skin temperature, and even limited knee flexion and extension activities. When symptoms such as pain and swelling on the inner side of the knee occur, it is recommended to consult a doctor in time and follow the doctor’s instructions.
