Knee Dislocation

Knee dislocations have historically been severe and potentially limb-threatening injuries. Over the last several decades, the diagnosis, treatment, and rehabilitation for knee dislocations have improved, leading to improved patient outcomes and knee function. A thorough physical examination including assessment of neurovascular status and the integrity of all ligaments and soft tissue structures of the knee is necessary for a comprehensive treatment plan. The use of stress radiographs, in combination with magnetic resonance imaging, is recommended to assess the functional status of the cruciate and collateral ligaments of the knee. An anatomic-based reconstruction approach within the acute treatment period following injury is recommended. In order to allow early functional rehabilitation, Patients who undergo anatomic-based reconstructions, followed by early postoperative rehabilitation focusing on protected range of motion and quadriceps strengthening, have shown optimal outcomes. With these principles, improved knee function and activity level can be expected; however, return to preinjury activity level cannot be expected.
