Pes anserinus (leg)

Pes anserinus
Muscles of the gluteal and posterior femoral regions. Area of pes anserinus is encircled at bottom. sartorius, gracilis and semitendinosus are labeled at bottom left.
Latin Pes anserinus
Anatomical terminology

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.[1]

Goose feet


The three muscles are (from anterior to posterior):[2]

The conjoined tendon lies superficial to the tibial insertion of the medial collateral ligament (MCL) of the knee.


A good mnemonic to remember the muscles which contribute tendons to this conjoined tendon and the innervations of these muscles is SGT FOT (sergeant FOT).

S- Sartorius G- Gracilis T- semiTendinosus (from anterior to posterior)

F- femoral nerve O- obturator nerve T- tibial nerve (one of the two component nerves of the sciatic nerve [the other being the common fibular (or common peroneal) nerve]. The sciatic nerve itself cannot technically innervate anything because it is merely the designation for the common sheath that encases the tibial and common fibular nerves.)

Notice the order of the muscles (S, G, T) follows the order of the innervating nerves which correspond to those muscles (F, O, T)

Clinical significance

It is a cause of chronic knee pain and weakness ("pes anserine bursitis").[3][4] Pes bursitis is a condition in which the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury a person can develop this ailment. This condition usually occurs in athletes from overuse. This pathology is characterized by pain, swelling, and tenderness.[3]

The semitendinosus tendon can be used in certain techniques for reconstruction of the anterior cruciate ligament.[5]
