The sartorius muscle can move the hip joint and the knee joint, but all of its actions are weak, making it a synergist muscle. [4] At the hip, it can flex, weakly abduct, and laterally rotate the femur. [4] At the knee, it can flex the leg; when the knee is flexed, sartorius medially rotates the leg.
The three tendons, from front to back, that conjoin to form the pes anserinus come from the sartorius muscle, the gracilis muscle, and the semitendinosus muscle. [1] [2] It inserts onto the proximal anteromedial surface of the tibia. [2] The pes anserinus is around 5 cm below the medial tibial joint line. [2]
Damage to the saphenous nerve and its infrapatellar branch is possible during medial knee surgery, potentially causing numbness or pain over the medial knee and leg. [7] As with all surgeries, there is a risk of bleeding, wound problems, deep vein thrombosis , and infection that can complicate the outcome and rehabilitation process.

Crossing on top of the lower part of the MCL is the pes anserinus, the joined tendons of the sartorius, gracilis, and semitendinosus muscles; a bursa is interposed between the two. The MCL's deep surface covers the inferior medial genicular vessels and nerve and the anterior portion of the tendon of the semimembranosus muscle, with which it is ...
The intermediate cutaneous nerve (middle cutaneous nerve) pierces the fascia lata (and generally the sartorius) about 7.5 cm below the inguinal ligament, and divides into two branches which descend in immediate proximity along the forepart of the thigh, to supply the skin as low as the front of the knee.
Cross-section of the upper right thigh. In this diagram, the anterior surface is at the bottom (labelled "A"). The anterior compartment is separated by a fibrous septum which is visible from the femoral artery and vein at the bottom, surrounding the sartorius muscle, and travelling to the profunda femoris artery adjacent to the femur (not labelled), from here to the sciatic nerve, and then ...
At its insertion the tendon is situated immediately above that of the semitendinosus muscle, and its upper edge is overlapped by the tendon of the sartorius muscle, which it joins to form the pes anserinus. The pes anserinus is separated from the medial collateral ligament of the knee-joint by a bursa.
