The vastus medialis is one of five muscles in the anterior compartment of the thigh. It is involved in knee extension, along with the other muscles which make up the quadriceps muscle. The obliquus genus muscle is the most distal segment of the vastus medialis muscle. 2  Its specific training plays an important role in maintaining patella position and limiting injuries to the knee. 3  With no clear delineation, it is simply the most distal fibers of the vastus medialis.
