<unk> , is an injury that is concerned with the kneecap.<unk><unk>  is more common than<unk>  dislocation and is just as disabling. In this condition, the<unk> repetitively subluxates and places strain on the medial restraints and excessive stress/tension on the patellofemoral joint.<unk><unk>  can be caused by osseous abnormalities, such as incorrect articulation of the femoral groove with the<unk>  trochlear dysplasia, or<unk> alta, which is a distance of greater than 20 mm between the tibial tubercle and the trochlear groove. It can also result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament, or a weakened vastus medialis obliquus. Symptoms are regulated by the amount of activity. Such pain is commonly caused by running and jumping sports and activities that place large forces on the patellofemoral joint.
