POSTERIOR CRUCIATE LIGAMENT (PCL) TEAR OR SAGGING

Isolated PCL tears are usually treated non-operatively even in elite athletes. Usual first aid measures are used, such as described as above. If diagnosed early, a specific PCL brace prevents the backwards sag of the tibia, facilitating healing. Early movement in the splint is essential. A strengthening program commences once healing is underway. Strengthening of the quadriceps or “thigh” muscle is critical as it has an action of pulling the tibia bone forwards, therefore, counterbalancing the posterior sag.

If the PCL and another ligament tears, early surgery is indicated. If the PCL tears off the bone, then it can be repaired. If the PCL suffers a mid-substance rupture, then it will need to be reconstructed. Some PCL tears result in ongoing instability or pain. These chronic tears may require a reconstruction as well.
