Abstract
In brief: Traumatic knee dislocation causing loss of popliteal artery flow can result in a be-low-knee (or higher) amputation if flow is not restored within six to eight hours. Loss of flow is rare in athletic trauma. However, the first physician to examine an athlete who has sustained a major knee injury or disruption must be alert to the possibility of the loss of arterial flow and take appropriate action. This means emergency transport of the athlete to a hospital for arteriogram, consultation with a vascular specialist, and definitive treatment. The author discusses various types of knee trauma and guidelines for immediate diagnosis and treatment. Most urgent is the restoration of popliteal artery flow as soon as possible in order to avoid amputation.
