The articularis genus (subcrureus) is a small skeletal muscle located anteriorly on the thigh just above the knee.

Structure

It arises from the anterior surface of the lower part of the body of the femur,^[1] deep to the vastus intermedius,^[2] close to the knee and from the deep fibers of the vastus intermedius.^[1]

Its insertion is on the synovial membrane of the knee-joint.^[1]

Blood supply

It is supplied by the lateral femoral circumflex artery.^[1]

Innervation

It is innervated by branches of the femoral nerve (L2-L4).^[1]

Variation

Flat, wispy and highly variable,^[3] sometimes consisting of several separate muscular bundles,^[4] this muscle is without a distinct investing fascia and ranges 1.5–3 cm in width.^[3]

It is usually distinct from the vastus intermedius, but occasionally blended with it.^[4]^{[needs update]}

Function

Articularis genus pulls the suprapatellar bursa superiorly during extension of the knee,^[2] and prevents impingement of the synovial membrane between the patella and the femur.^[1]
