AbstractThis case highlights a staged operative approach for a patient who sustained bilateral knee dislocations and subsequent staged operative treatment and rehabilitation. This patient underwent bilateral multiligamentous knee reconstructions and left-sided peroneal nerve allografting because of complete peroneal nerve palsy. The initial treatment was bilateral medial collateral ligament reconstructions, posterolateral corner reconstructions, and capsular repairs with left leg peroneal nerve allografting and repair of avulsed biceps femoris tendon. The patient underwent physical therapy following the first stage procedure until he regained appropriate motion and soft tissue healing occurred. Subsequently, combined anterior cruciate and posterior cruciate ligament reconstructions were performed in a staged fashion to allow one leg to fully bear weight for rehabilitation purposes. With the help of a multidisciplinary surgical and rehabilitation team, the patient has regained the stability of his knees and achieved acceptable functional outcomes. A staged systematic approach to multiligamentous bilateral knee reconstruction can provide optimal pain management, obtain initial joint stability, minimize complications, and achieve acceptable functional outcomes. Surgical techniques to first restore medial and lateral structures can be utilized to provide initial valgus and varus stability while allowing for knee mobilization and, eventually, in-line ambulation, before staged anterior and posterior cruciate ligament reconstructions. This case demonstrates a multistaged approach to bilateral knee dislocations with favorable outcomes in a 23-year-old active duty patient.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2022.
