Abstract:

An isolated posterior cruciate ligament injury is a difficult clinical and surgical problem. Most authors agree that multidirectional rotatory instability of a knee resulting from either medial or lateral ligamentous laxity in combination with a posterior cruciate ligament (PCL) injury requires surgical stabilization. However, indications for surgical reconstruction of an isolated posterior cruciate ligament injury still remain controversial. This lack of agreement over the surgical indications for this injury appears to stem from a lack of clear understanding of the natural course of PCL-deficient knee, and current limitations in surgical technique to reproduce posterior stability in a predictable fashion.
