The management of multiligament knee injury is a complex process starting with the adequate identification of the injury. A detailed physical and radiographic examination with a thorough understanding of knee anatomy is crucial to assess all damaged structures: anterior cruciate ligament, posterior cruciate ligament, posteromedial corner including the medial collateral ligament, and posterolateral corner including the lateral collateral ligament. Several surgical techniques have been developed throughout the years to adequately address these ligament insufficiencies. In this surgical technique description, we describe a reproducible method for the assessment and surgical management of a knee dislocation (KDIV) injury. Our approach includes using anatomic single-bundle cruciate ligament reconstructions with modified Bosworth technique for medial-side injuries and a combination of Müller popliteal bypass and Larson figure-of-8 techniques for posterolateral corner injuries. The orders of surgical steps is described concisely, and technical controversies such as graft choice, tunnel positioning, and sequence of graft fixation are discussed in detail.
