| The posterior cruciate ligament (PCL) is a powerful ligament extending from the top-rear surface of the tibia to the bottom-front surface of the femur. The ligament prevents the knee joint from instability in the back of the joint. The PCL is usually injured by hyperextension (overextending the knee), or a direct blow to the flexed knee (such as from "dashboard knee" in a car accident). Learn More |
