Injuries of the posterolateral corner of the knee have historically been difficult to treat. The primary stabilizers of the posterolateral corner include the fibular collateral ligament, popliteus tendon, and popliteofibular ligament. Proper treatment of these injuries requires complete clinical workup including stress radiographs, alignment imaging, and magnetic resonance imaging. Recent developments in the understanding of the bony and soft tissue anatomy of the posterolateral corner have allowed for the development of verified anatomic based reconstruction techniques. These techniques, when performed in the acute window, have been shown to have good outcomes in patients as they restore the native kinematics of the knee. Early rehabilitation should begin on postoperative day one and focus on protected range of motion and quadriceps strengthening.
