Vastus medialis oblique: an anatomic and physiologic study.

The lower part of the vastus medialis, which originates chiefly from the tendon of the adductor magnus, has been designated as the "vastus medialis oblique." This muscle is peculiar to man. The fibers of the muscle are mostly horizontal; therefore they are in a unique position to stabilize the patella against the femur in the later stages of extension of the knee. This article details the anatomic and physiologic features of the vastus medialis oblique. Copyright 2013, SLACK Incorporated.
