Pes anserinus (goose foot) refers to the conjoined tendons of three muscles that insert onto the anteromedial (front and inside) surface of the proximal extremity of the tibia. The muscles are the sartorius gracilis and semitendinosus. The name goose foot arises from the three pronged manner in which the conjoined tendon inserts onto the tibia.
