Ipsilateral hip and knee dislocation.

Abstract

Hip and knee dislocations individually are two of the relatively limited orthopaedic emergencies. Long-term results of treatment of these two types of injury are associated with avascular necrosis of the femoral head, knee instability, and knee stiffness. Correct early diagnosis, including arteriography in the case of knee dislocation, is crucial. Prompt treatment consisting of closed or open reduction of the dislocations is necessary. Additional treatment involving knee ligament reconstruction is warranted to maximize knee function in healthy, active patients. Simultaneous occurrence of ipsilateral hip and knee dislocations is a particularly morbid injury. We report such a case to emphasize that early, aggressive treatment and extensive physical therapy can result in a functional and painless lower extremity.
