What Is A Posterior Cruciate Ligament (PCL) Injury?

The posterior cruciate ligament (PCL) is located in the back of the knee and is one of several ligaments that connect the femur (thighbone) to the tibia (shinbone). The posterior cruciate ligament keeps the tibia from pivoting backwards too far.

An injury to the posterior cruciate ligament requires a powerful force. Common PCL injuries include; a bent knee impacting the dashboard in a car accident; a football player falling with the force of their body weight on a bent knee.
