What is PCL Tear?

The posterior cruciate ligament (PCL) is one of the four critical ligaments in the knee. It is located in the back of the knee and connects the femur (thigh bone) to the tibia (shin bone). The PCL helps stabilize the knee joint and keep it from hyperextending (straightening too much).

 PCL tears are relatively rare, accounting for only 2-8% of all knee ligament injuries. They most commonly occur in athletes who participate in contact sports, such as football or hockey. PCL tears can also occur due to a direct blow to the knee, a fall onto the knee, or a car accident.

Sporting injuries like hyperextension and twisting can also cause a PCL tear.

 A PCL tear may include pain and swelling in the knee, knee instability, and difficulty straightening the knee. A popping or snapping sound may be heard at the injury. The pain in the back of the knee is far worse and more severe. Pain in the front side may occur after a week or two of the injury. An MRI is typically used to confirm the diagnosis.

Why are ACL tears more common than PCL?

The ACL (Anterior Cruciate Ligament) and PCL (Posterior Cruciate Ligament) are two primary ligaments in the knee that work in unison to give stability. These sites are vulnerable to severe tears, particularly in athletes. Both ACL and PCL tears may appear to have similar symptoms in their early stages. The ligaments have distinct features that make these tears differ in treatment and the extent of the injury.

 Usually, a sports mishap is involved in the ACL and PCL tears. A sudden stop or rapid change in direction can cause injury to the ACL. These movements are typical in sporting activities; therefore, an ACL tear is very high. On the other hand, PCL tears occur when the knee is bent during a fall or in a car accident. A severe blow to the shinbone can also cause PCL injury.

 Most PCL tears can recover independently without surgery. However, the treatment for an ACL tear is far more extensive.

How to repair and prevent a PCL tear?

Treatment for a PCL tear may include PRICE (Protection, rest, ice, compression, elevation), physical therapy, and a knee brace. Surgery is rarely needed.

 To prevent a PCL tear, it is essential to warm up before participating in any physical activity. Wearing proper shoes and using proper techniques can also help to avoid injury. Bracing and crutches are recommended in most cases that involve PCL tears.
