Polyethylene wear debris from metal-on-polyethylene articulations are one of the main causes of periprosthetic bone loss and non-infectious loosening in total hip arthroplasty. Ceramic articulations have a very low wear rate when measured in the laboratory and the investigator's hypothesis is that hip arthroplasty with an all ceramic articulation will have less osteolysis and wear in addition to equally good fixation and clinical outcome compared to the same hip arthroplasty design with a metal-on-polyethylene joint.
