Knee Posterolateral Corner Reconstruction with a Single Tendon

Knee posterolateral corner (PLC) injuries are troublesome conditions and are always involved in complicated knee-ligament injuries. Various surgical techniques have been reported to address these conditions, in either an open or an arthroscopic manner. However, a simple and effective method is still being pursued. We introduce a mini-invasive PLC reconstruction technique in which a single tendon is used to reconstruct the lateral collateral ligament, the popliteofibular ligament and the popliteal tendon simultaneously. The critical points of this technique are proper location and creation of the tibial, fibular and femoral tunnels, proper passing and setting of the tendon graft, as well as protection of the peroneal nerve. Our clinical experience indicates that this technique is easy to perform and effective. We consider that the introduction of this technique will provide more reasonable options when PLC reconstruction is indicated.
