What is Goosefoot (Pes Anserine) Bursitis of the Knee?

Bursae are small fluid-filled sacs that serve to provide cushioning and reduce friction in joints. The pes anserine bursa is found in the knee joint, between the tibia and the pes anserinus tendons that connect the tibia and hamstring muscles. This group of tendons were named after their appearance — Pes anserinus is Latin for "goosefoot." Goosefoot bursitis of the knee is a potentially painful condition in which the pes anserine bursa becomes inflamed, which can affect the knee's range of motion.

One of the most common symptoms is gradually developing pain two to three inches below the knee joint, on the inner side of the knee. The pain may increase with physical activity. Swelling and mobility loss may also occur in the affected area.
