Surface analysis on revised hip implants with stem taper for wear and failure incidence evaluation: A first investigation

As revision surgeries of total hip arthroplasty are going to increase, success or failure of revised implants is a fundamental aspect in the orthopaedic field. Today, slight is known about the success rate of revised total hip arthroplasty when the femoral head is substituted on a retained stem.
