Posterior Instability of the Knee - Posterior Cruciate Ligament Injury

What are the treatments for the injury?

Treatment depends on the degree of instability, the person's age, and anticipated future activities. Initial treatment is a brief period of RICE (rest, ice, compression, and elevation). Non-steroidal anti-inflammatory medications (NSAIDs) can help relieve pain. An exercise program may help to regain motion and strength of the knee, especially the upper thigh. For the young athlete, surgical reconstruction of the ligament may be appropriate. In an older, non-athletic person, a non-surgical approach may be chosen, such as a brace. Physical therapy is generally ordered after surgery.

What are the side effects of the treatments?

NSAIDs may have adverse effects on the stomach, liver, or kidneys.

What happens after treatment for the injury?

PCL injury can result in serious damage to the nerves or the artery behind the knee. Treatment may not be successful in restoring stability to the knee. Stiffness and weakness of the knee may remain. Infection is possible after any operation.

The person will be asked to observe for symptoms of instability, with repeated episodes of pain, swelling, giving way, or locking of the knee.
