Acute injury ischemia of the popliteal artery is the most serious and most common immediate complication of knee dislocations with an average rate of 30%. We report here a retrospective study of twelve patients spread over four years from January 2014 to December 2017. CT angiography was the key examination to confirm the diagnosis. Each patient received a surgical repair of the arterial lesion more or less associated with a ligamentous plasty later. The evolution was favorable in ten patients. Amputation has been reported in two patients following failure of surgical repair. Five patients subsequently benefited from ligament repair. In the literature and for most authors the absence of initial vascular clinical abnormality does not exclude a vascular lesion, since the coexistence of initially preserved pulse and popliteal artery lesions varies from 18 to 52% depending on the series with an average of 30%. Surgical repair of the vascular lesion with or without the intervention of a venous graft is the emergency rescue procedure to avoid progression to amputation of the limb
