The sartorius, gracilis, and semitendinosus muscles attach to the tibia in a three-pronged pattern on the tibia, so their combined tendons of insertion are often termed the pes anserinus (Latin for “goose foot”).
In the upper one-third of the thigh, the medial margin of the sartorius forms the lateral margin of the femoral triangle.
In the middle one-third of the thigh, the sartorius forms the anterior wall of the adductor canal.
