Poplital artery transection injury is potentially catastrophic, or even life-threatening. Severe traumas, including open fracture, gunshot, stabs, and knee dislocation and complex fracture of proximal tibia or distal femur, are the common causes of high rate of amputation due to popliteal artery trauma.

A 30-year-old male presented with popliteal artery transection injury associated with minimally displaced tibial plateau fracture. He presented to the emergency department, 6 h after fall from ground into a 1-m height hole. Physical examination suggested acute ischemia, with signs of paleness, coldness, anesthesia, hemorrhagic bullae below the right knee level. There was severe swelling and ecchymosis in popliteal fossa and around the leg with significant calf tenderness and pedal edema. Tibialis posterior, dorsalis pedis, and popliteal arterial pulses were not palpable. Radiograph suggested minimally displaced tibial plateau fracture with no evidence of knee dislocation. The patient was taken up for emergency surgery after consultation with vascular surgeon. During the closed reduction external fixation and compartment decompression, popliteal artery trunk was found transected and end-to-end repair was performed. During the post-operational period, no complication was developed and the patient was followed-up for 1 year. At the one-year follow-up, he acquired good stability of his right knee with full range of motion.

Significant swelling and ecchymosis should alert the surgeons to the possibility of vascular injury in knee joint injury, even if there is no fracture or dislocation, or fracture is minimally displaced.
