How is a PCL rupture diagnosed?

Diagnosing PCL injury can be more difficult than diagnosing ACL injury, as findings are generally subtle. PCL injury may be suspected when there is a history of recent knee trauma with swelling and giving way. During examination, the injured knee may appear to sag backwards when bent, and it may hyperextend. Usually the diagnosis is confirmed with an MRI scan. Occasionally an MRI scan can look normal, especially if the injury was quite some time ago. Isolated PCL injuries can often be managed without surgery. The ligament does not always heal completely, however near full function from the knee can still be achieved with rehabilitation. Non-surgical treatment will often require a period of knee bracing, and you may benefit from some physiotherapy.
