Ruptured Posterior Cruciate Ligament
The Posterior Cruciate Ligament (PCL) is located in the middle of the knee and works in unison with the Anterior Cruciate Ligament (ACL) to keep the femur and tibia in place. A ruptured PCL is caused by hyperextension of this ligament in the knee. Symptoms may include swelling and tenderness in the area behind the knee accompanied by pain and instability at the knee joint.
