HOT TOPIC: Knee Dislocation: Controversies and Future Directions

Abstract

Knee dislocations are ligamentous disruptions that result in loss of continuity of the tibiofemoral articulation. Most knee dislocations are the result of high-energy trauma, and involve tears of both the anterior cruciate ligament and the posterior cruciate ligament, with variable collateral ligament damage. The diagnosis of these injuries has changed considerably, as it has been recognized that most patients present with the knee spontaneously reduced. Successful outcome with these challenging injuries requires combining complex knee reconstruction techniques from sports medicine with a firm understanding of the management of high-energy soft-tissue injuries from trauma. This article will review relevant anatomy and diagnostic criteria for knee dislocations, in addition to reviewing several management options for this complex injury.
