MPFL – The Little Ligament That Could
The medial patellofemoral ligament (MPFL) is one of the many ligaments in and around the knee joint. As its name suggests, the ligament runs from the patella (kneecap) to the femur (thigh bone). It plays a very important role in stabilizing the patella during knee movement. Injury to the MPFL often occurs during non-contact twisting motions (eg – a sudden change of direction, pivoting) which can cause the patella to dislocate laterally. Symptoms following a patellar dislocation include pain, swelling, stiffness, and weakness in the knee. Treatment typically follows the PRICE protocol of protection, rest, ice, compression, and elevation. NSAIDs can also help decrease symptoms.
