Surgical treatment of acute and chronic anterior cruciate ligament/posterior cruciate ligament/lateral sided injuries of the knee

Combined bicruciate and posterolateral corner injuries are among the most challenging reconstructive problems in orthopedics. The potential for severity of injury (including the soft tissue envelope), chance for multi trauma, peroneal nerve palsy, and complex gait abnormalities with varus thrust add to the already difficult ligamentous reconstructive options. Use of magnetic resonance, examination under anesthesia, and rehabilitation potential will direct the surgeon to individualize treatment to each specific injury pattern. This chapter outlines the authors' experiences with combined bicruciate injuries and the posterolateral comer.
