The posteromedial corner is the region towards the back of the knee on the inner side.

Posteromedial corner
The semimembranosus expansion (SME) is the expansion of the semimembranosus tendon, and inserts the femur, tibia and the medial meniscus. Other structures of the posteromedial corner include the posterior oblique ligament, the medial collateral ligament and the tendon of the medial head of the gastrocnemius muscle.
