The pes anserinus ("goose's foot") is the insertion of the conjoined tendons of three muscles onto the anteromedial proximal tibia bone (from anterior to posterior):^[1]

• sartorius
• gracilis
• semitendinosus

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

[edit] Mnemonic

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

S- Sartorius G- Gracilis T- semiTendinosus (from lateral to medial)

F- femoral nerve O- obturator nerve S- sciatic nerve

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

[edit] Clinical significance

It is a major cause of chronic knee pain and weakness ("pes anserinus bursitis").^[2][3]
