Combined Anterior Cruciate Ligament and Posterolateral Corner Reconstruction by Hamstring Tendon Autografts Through a Single Femoral Tunnel by Graft-to-Graft Suspension and Fixation

An untreated posterolateral corner (PLC) injury in patients with a torn anterior cruciate ligament (ACL) may be a leading cause of ACL reconstruction failure. Combined ACL and PLC reconstruction is discussed in few studies in the literature. Femoral tunnel intersection in combined reconstruction has been reported to be high. Short grafts may render combined reconstruction undoable. This Technical Note describes a technique that allows a combined ACL and PLC reconstruction. The ACL graft is a 4-stranded hamstring tendon graft from 1 limb. The PLC graft is a doubled semitendinosus tendon graft from the contralateral side. One femoral tunnel is used connecting the femoral attachment of the PLC on the lateral wall of the lateral femoral condyle to the anatomic femoral ACL footprint on the medial wall of the lateral femoral condyle. The PLC graft is suspended on the ACL graft to be anchored on the cortex of the lateral femoral condyle with added fixation by an interference screw (Arthrex, Naples, FL). The PLC graft limbs are used for open reconstruction of the fibular collateral ligament, popliteus tendon, and popliteofibular ligament. This Technical Note describes a technique of combined ACL and PLC reconstruction with hamstring tendon autografts through a single femoral tunnel using graft-to-graft suspension and fixation.
