Excerpt

A knee dislocation can be defined as complete congruency loss between the distal femoral and proximal tibial articular surfaces. Bicruciate or multiligamentous injuries can also be categorized as knee dislocation due to the mechanism of injury. A knee dislocation is a potentially devastating injury and is often a surgical emergency. This injury requires prompt identification, evaluation with appropriate imaging, and consultation with surgery for definitive treatment. Vascular injury and compartment syndrome are complications that the clinician should not miss in the workup of a knee dislocation. This is in distinct contrast to patellar dislocations, which generally do not require immediate surgical or vascular intervention.
