The Articularis genu (Subcrureus) is a small muscle, usually distinct from the Vastus intermedius, but occasionally blended with it; it arises from the anterior surface of the lower part of the body of the femur, and is inserted into the upper part of the synovial membrane of the knee-joint.

Articularis genu pulls the suprapatellar bursa during extension of the knee, allowing the patella to move freely without friction with the femur.

It sometimes consists of several separate muscular bundles.
