{Abstract}: Amputation secondary to vascular complications of recurrent dislocations after total hip arthroplasty (THA) is an extremely rare. We describe an unusual case of above-knee amputation resulting from vascular complications after recurrent dislocations of a THA. A 63-year-old male patient with walking pain and limp has a history of acetabular fracture and central dislocation of the femoral head. He was diagnosed as post-traumatic arthritis and subluxation of the femoral head and suffered from four similar dislocations in 210 days after the THA. The patient received conservative treatment after every hip dislocation. However, four months after the fourth reduction, the emergent femoral artery and popliteal artery exploration and catheter thrombectomy were performed at another hospital. An ipsilateral above-knee amputation was done after sepsis and failure of the revascularization procedure. Clinicians should be cognizant that above-knee amputation resulting from vascular complications after recurrent dislocations of a THA may occur. The lack of adherence to critical treatment may have led to the severe outcome of amputation. In conclusion, patient education and compliance are essential for both the treatment of hip dislocations and arterial occlusion. More active and effective measures should be used to prevent such catastrophic events.
