Knee dislocations are rare but in a high percentage may cause severe and devastating neurovascular complications. Damage of the common peroneal nerve is the most frequent injury. The popliteal artery is more prone to be affected in posterior knee dislocation and whithin multiligament traumatic injury. We present a case of anterior tibio-femoral dislocation associated with acute ischemia due to popliteal artery occlusion that needed emergent surgical intervention for revascularisation of the left lower limb through bypass. Postoperative outcome was satisfactory with pedal and posterior tibial pulses recovery. A high grade of clinical suspicion is needed for early detection of vascular complications. Delay in vascular intervention increases dramatically the risk of irreversible injury and the need of amputation.

Keywords : Dislocation; knee; popliteal artery; ischemia; femoro-popliteal by pass.
