Cruciate ligament injury - posterior; PCL injury; Knee injury - posterior cruciate ligament (PCL); Hyperextended knee
At first, a PCL injury is treated by:
Limit physical activity until the swelling is down, motion is normal, and the pain is gone. Physical therapy can help you regain joint and leg strength. If the injury happens suddenly (acute) or you have a high activity level, you may need surgery. This may be either knee arthroscopy or "open" surgical reconstruction.
Age has an effect on treatment. Younger patients are more likely to have problems without surgery, because chronic instability may lead to arthritis symptoms many years later. Which patients need surgery is controversial, because many people seem to do well without surgery. Injuries in which the bone is pulled off with the ligament, or multiple ligaments are injured need to be repaired with surgery.
PCL injuries are commonly associated with other ligament injuries or knee dislocation. It is important to have your knee examined for other injuries. Some of these injuries need to be treated urgently.
Call your health care provider if:
A lot of PCL injuries are associated with other ligament injuries or severe knee trauma. You should be checked early for these other conditions.
