A safe postero-medial approach to posterior cruciate ligament avulsion fracture.

The posterior cruciate ligament (PCL) plays a major role in knee stabilization, and clinical studies have shown an increase in incidence of its injury. Due to the surrounding neurovascular elements in the popliteal space, open approaches to repair such injury are difficult to perform. The "safe postero-medial approach" to PCL avulsion fracture is a simple approach, does not require exploration of the neurovascular elements, and produced satisfactory results in the majority of patients.
