Management of Multiligament Knee Injury

Multiligament knee injuries are defined as injuries to at least two of the four major ligaments in the knee: anterior cruciate ligament, posterior cruciate ligament, lateral collateral ligament (and posterolateral corner) and medial collateral ligament (and posteromedial corner). Multiple ligament knee injuries that results from high energy trauma, may have nerve and vascular injuries, therefore neurovascular examination with clear documentation of capillary refill time, distal pulses, function of all lower limb compartments and common peroneal and tibial nerve function should be performed. Before definitive treatment performed, we have to classified the multiligament injury according to the energy of the injury and the anatomic injured structures. MRI still recommended to know about the ligaments injury. The goal and our priority treatment is to obtain functional stability of the knee without the loss of motion or stiffnes that can lead to longterm pain, weakness, and the subsequent osteoarthritis.
