Posterior Cruciate Ligament Tear

Posterior cruciate ligament (PCL), one of four major ligaments of the knee is situated at the back of the knee. It connects the thighbone (femur) to the shinbone (tibia). The PCL limits the backward motion of the shinbone.

PCL injuries are very rare and are difficult to detect than other knee ligament injuries. Cartilage injuries, bone bruises, and ligament injuries often occur in combination with PCL injuries. Injuries to the PCL can be graded as I, II or III depending on the severity of injury. In grade I the ligament is mildly damaged and slightly stretched, but the knee joint is stable. In grade II there is partial tear of the ligament. In grade III there is complete tear of the ligament and the ligament is divided into two halves making the knee joint unstable.

The PCL is usually injured by a direct impact, such as in an automobile accident when the bent knee forcefully strikes the dashboard. In sports, it can occur when an athlete falls to the ground with a bent knee. Twisting injury or overextending the knee can cause the PCL to tear.

Patients with PCL injuries usually experience knee pain and swelling immediately after the injury. There may also be instability in the knee joint, knee stiffness that causes limping, and difficulty in walking.

Diagnosis of a PCL tear is made on the basis of your symptoms, medical history, and by performing a physical examination of the knee. Other diagnostic tests such as X-rays and MRI scan may be ordered. X-rays are useful to rule out avulsion fractures wherein the PCL tears off a piece of bone along with it. An MRI scan is done to help view the images of soft tissues better.

Treatment options may include non-surgical and surgical treatment. Non-surgical treatment consists of rest, ice, compression, and elevation (RICE protocol); all assist in controlling pain and swelling. Physical therapy may be recommended to improve knee motion and strength. A knee brace may be needed to help immobilize your knee. Crutches may be recommended to protect your knee and avoid bearing weight on your leg.

Generally, surgery is considered in patients with dislocated knee and several torn ligaments including the PCL. Surgery involves reconstructing the torn ligament using a tissue graft which is taken from another part of your body, or a cadaver (another human donor). Surgery is usually carried out with an arthroscope using small incisions. The major advantages of this technique include minimal postoperative pain, short hospital stay, and a fast recovery. Following PCL reconstruction, a rehabilitation program will be started that helps you resume a wider range of activities. Usually, a complete recovery may take about 6 to 12 months.
