Definition
The semimembranosus bursa is a synovial-lined structure located between the semimembranosus tendon and the medial head of the gastrocnemius muscle. It extends on the superficial surface of the tibial collateral ligament and mis sometime called "semimembranosus-tibial collateral bursa".
When filled with fluid, the semimembranosus bursa has a remarquable "inverted-U" shape, which allows its easy identification.
