What it is
Long, slender strap along the inner thigh, from the body and inferior ramus of the pubis to the upper medial surface of the tibia (pes anserinus), between the insertions of sartorius and semitendinosus.
Function
Adducts the hip, flexes the knee and medially rotates the flexed leg.
Size
About 40-45 cm long, 3-4 cm wide at the top.
Clinical note
Largely expendable, so it is a favourite free muscle flap in reconstructive surgery and its tendon a graft for ligament reconstruction.
