Anatomical reconstruction of the Posterolateral Corner of the knee preserving dynamic function of the popliteus tendon complex
Almost cases of Posterolateral Corner (PLC) injuries are combined injuries involving the anterior or posterior cruciate ligament. Although numerous techniques of PLC reconstruction have been reported, it is unknown whether these techniques reconstruct PLC sufficiently. The anatomy of PLC is complex...

description | Almost cases of Posterolateral Corner (PLC) injuries are combined injuries involving the anterior or posterior cruciate ligament. Although numerous techniques of PLC reconstruction have been reported, it is unknown whether these techniques reconstruct PLC sufficiently. The anatomy of PLC is complex of tendon-muscle and ligament. The major structures are the fibular collateral ligament (FCL) and the Popliteus Tendon Complex. The latter comprises the popliteus tendon-muscle and the popliteo-fibular ligament (PFL). The FCL and PFL are static stabilizers, whereas the popliteus tendon-muscle is a dynamic stabilizer. The most of current PLC reconstructions statically restore all component parts, therefore not true “anatomically”. We describe an operative technique to reconstruct PLC anatomically. Our technique preserves dynamic stability of the popliteus tendon-muscle and reconstructs the PFL and FCL selectively.Semitendinosus tendon is harvested, and almost used for the anterior or posterior cruciate ligament reconstruction. Gracilis tendon or contralateral semitendinosus tendon is used for PLC. Femoral bone tunnel for FCL is prepared at anatomical insertion. Fibular bone tunnel is prepared to connect PFL insertion with FCL insertion. One end of the graft is sutured to the popliteus tendon. The other end is passed though the fibular tunnel, and fixed at the femoral tunnel. The interference screws are used at each tunnel. One half of the graft composes PFL part, the other half composes FCL part. Advantages of this technique are preservation of dynamic popliteus tendon-muscle function, and simplifying preparation. |
