Total hip arthroplasty following an ipsilateral above knee amputation.

Total hip arthroplasty in patients with previous above knee amputations is rare. We present a unique case where the patient had only 130 mm of proximal femur remaining following a previous traumatic above knee amputation. The short segment of femur meaning a conventional femoral stem could not be used. We describe the technique of total hip arthoplasty for this patient using a mini hip prosthesis and report a successful clinical and radiological outcome at 2 years post-op.
