Posterior cruciate ligament injuries

Abstract

Posterior cruciate ligament (PCL) injuries occur following both high-velocity trauma (motor vehicle collisions) and low-velocity trauma (sporting injuries) with the most common cause being high-velocity trauma resulting in so-called ‘dash board injuries’. In majority of the cases, clinical examination will reveal the presence of a PCL tear; however, magnetic resonance imaging remains the imaging modality of choice if the diagnosis is in doubt. For the most part, isolated PCL tears are relatively benign and can be treated conservatively. PCL avulsion injuries or grade III ruptures may require operative intervention. Postoperative rehabilitation is also an important part of the healing process.
