The lateral collateral ligament originates on the lateral femoral condyle proximal to the insertion of the popliteus, runs superficial to popliteus, and inserts anterolaterally to the popliteofibular ligament on the fibula. The posterolateral corner (PLC) of the knee has received much attention as a restraint to control external rotation and posterior translation of the tibia in conjunction with the PCL. Injuries to the PLC rarely occur in isolation, less than 5% of the time. LaPrade et al performed anatomic dissections on 10 cadavers and provide a detailed description of the anatomic attachments of the PLC components, with the goal of helping guide surgeons performing anatomic reconstructions of an injured PLC. They found the lateral collateral ligament was the most anterior structure inserting on the fibular head. Stannard et al found that initial success rates of direct repair of the PLC were significantly inferior to early reconstruction. Illustration A and B demonstrate the structures of the PLC. Illustration C shows an MRI typical for this injury.
