Another study showed anterior subluxation of the semitendinosus and gracilis tendons over the semimembranosus insertion at the posteromedial corner of the tibia during active terminal extension (2). Action: Extends the thigh, flexes the knee, and also rotates the tibia medially, especially when the knee is flexed. The muscle can also aid in counteracting the forward bending at the hip joint. The semimembranosus muscle inserts onto the medial condyle of the tibia. The muscle inserts via a long tendon overlying the semimembranosus muscle at the upper part of the medial surface of the tibia behind the insertion of the sartorius and distal to the insertion of the gracilis (pes anserine). 2012;32:173-83 The purpose of this study is to investigate the distal insertions of the semimembranosus tendon with MR imaging, correlated with findings in cadavers.
