Medial patellofemoral ligament

Ligament of the knee

The medial patellofemoral ligament (MPFL) is one of several ligaments on the medial aspect of the knee. It originates in the superomedial aspect of the patella and inserts in the space between the adductor tubercle and the medial femoral epicondyle. The ligament itself extends from the femur to the superomedial patella, and its shape is similar to a trapezoid. It keeps the patella in place, but its main function is to prevent lateral displacement of the patella.
