The vastus medialis oblique muscle is described to have an important role in functional stabilization of the patella against lateral vector force.
2.
The MPFL arises from the fibers of the vastus medialis obliquus muscle and attaches distally to the superior medial aspect of the patella.
3.
It can also result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament, or a weakened vastus medialis obliquus.
4.
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.
5.
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.
6.
The anterior compartment of thigh contains the sartorius muscle and the four quadriceps : the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis, along with the articularis genus.
7.
From the medial lip of the linea aspera and its prolongations above and below, the vastus medialis arises; and from the lateral lip and its upward prolongation, the vastus lateralis takes origin.
8.
Due to being the deeper middle-most of the rectus femoris can, nor is it accessible to manipulate with massage therapy to stretch the fibres sideways as the vastus lateralis and vastus medialis are.
9.
Additionally, the loss of explosive leg power was associated with a substantial reduction in the electromyography ( EMG ) activity of the m . rectus femoris, m . vastus lateralis, and m . vastus medialis.
10.
The medial surface includes the portion between the medial border and the linea aspera; it is continuous above with the lower border of the neck, below with the medial side of the medial condyle : it is covered by the Vastus medialis.
