Knee pain is thought to be primarily associated with specific quadriceps muscle weakness or fatigue, especially in the vastus medialis obliquus (VMO).It is known that fatigue can be caused by many different mechanisms, ranging from the accumulation of metabolites within muscle fibers to the generation of an inadequate motor command in the motor cortex. [4]
The vastus medialis arises medially along the entire length of the femur, and attaches with the other muscles of the quadriceps in the quadriceps tendon. [1] The vastus medialis muscle originates from a continuous line of attachment on the femur, which begins on the front and middle side (anteromedially) on the intertrochanteric line of the femur.
The vastus medialis muscle is on the medial side of the femur (i.e. on the inner part thigh). [1] The vastus intermedius muscle lies between vastus lateralis and vastus medialis on the front of the femur (i.e. on the top or front of the thigh), but deep to the rectus femoris muscle. Typically, it cannot be seen without dissection of the rectus ...
The anterior compartment is one of the fascial compartments of the thigh that contains groups of muscles together with their nerves and blood supply. The anterior compartment contains the sartorius muscle (the longest muscle in the body) and the quadriceps femoris group, which consists of the rectus femoris muscle and the three vasti muscles – the vastus lateralis, vastus intermedius, and ...
Posterior division supplies the rectus femoris muscle, the three vastus muscles – (vastus medialis, vastus lateralis, and vastus intermedius), and the articularis genus muscle. The articularis genus is supplied by a branch of the nerve to vastus intermedius.
Between the vastus lateralis and the adductor magnus two muscles are attached: the gluteus maximus muscle inserted above, and the short head of the biceps femoris muscle originating below. Between the adductor magnus and the vastus medialis four muscles are inserted: the iliacus muscle and pectineus muscle above;
The quadriceps muscles consist of the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These quadriceps muscles are innervated by the femoral nerve. [ 1 ] The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when ...
Deep to sartorius and its fascia is the adductor canal, through which the saphenous nerve, femoral artery and vein, and nerve to vastus medialis pass. [ 3 ] Innervation
