Posterior Cruciate Ligament Injuries
The posterior cruciate ligament (PCL) is the strongest ligament in the knee joint. Ligaments are thick, strong bands of tissue that connect bone to bone. The PCL runs along the back of the knee joint from the bottom of the thighbone (femur) to the top of the lower leg bone (tibia).
The PCL helps keep the knee joint stable, especially the back of the joint. An injury to the PCL could involve straining, spraining, or tearing any part of that ligament. The PCL is the least commonly injured ligament in the knee.
The main cause of PCL injury is severe trauma to the knee joint. Often, other ligaments in the knee are affected as well. One cause specific to PCL injury is hyperextension or over straightning of the knee. This can occur during athletic movements like jumping.
PCL injuries can also result from a blow to the knee while it is flexed, or bent. This includes landing hard during sports or a fall, or from a car accident.
Mechanism of PCL Injury
The physiotherapy and bracing regime may vary from patient to patient, and in large part depends upon whether posterolateral corner or other ligament reconstruction has been necessary. The description below is the usual one employed but your Consultant will specifically outline the exact protocol to you prior to surgery.
