Posterior cruciate ligament reconstruction involves using graft material to refashion and replace a damaged posterior cruciate ligament.

Posterior cruciate ligament injury
Posterior cruciate (PCL) injuries are typically combined with other ligamentous, meniscal and cartilage injuries. Isolated grade I or II PCL injuries can usually be treated without surgery. However, when more severe tears occur together with other ligament or meniscus injury surgery is indicated.
