The posterolateral corner can be rebuilt with donor tissue by passing a tunnel through the proximal fibular head, underneath the tibial band, and into the insertion just slightly superior to the popliteus and lateral collateral ligament insertion, slightly below Blumensaat’s line on the lateral aspect of the femur. This surgical technique is performed as an outpatient procedure, and we usually do it in combination with ACL reconstruction or PCL reconstruction for the patients who have posterolateral corner instability. The rehabilitation of the posterolateral corner reconstruction follows a very specific plan.
