vastus medialis การใช้

The vastus medialis oblique muscle is described to have an important role in functional stabilization of the patella against lateral vector force.
The MPFL arises from the fibers of the vastus medialis obliquus muscle and attaches distally to the superior medial aspect of the patella.
It can also result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament, or a weakened vastus medialis obliquus.
The patella is stabilized by the insertion of the horizontal fibres of vastus medialis and by the prominence of the lateral femoral condyle, which discourages lateral dislocation during flexion.
Anterior compartment muscles of the thigh include pectineus, sartorius, and the four muscles that comprise the quadriceps muscles-rectus femoris, vastus medialis, vastus intermedius and vastus lateralis.
