Semimembranosus-tibial collateral ligament bursa

Last revised by Dr Mostafa El-Feky on 29 Apr 2022

The semimembranosus-tibial collateral ligament bursa, also known more simply as the semimembranosus bursa, is located at the posteromedial aspect of the knee at the medial aspect of the semimembranosus tendon.  When filled with fluid, the semimembranosus-tibial collateral bursa has an unmistakable "inverted-U" shape, which allows its easy identification.

It is distinct from the pes anserinus bursa, which is more closely related to the deep aspect of the pes anserinus tendons.
