Large head metal-on-metal cementless total hip arthroplasty versus 28mm metal-on-polyethylene cementless total hip arthroplasty: design of a randomized controlled trial

Abstract Background Osteoarthritis of the hip is successfully treated by total hip arthroplasty with metal-on-polyethylene articulation.Polyethylene wear debris can however lead to osteolysis, aseptic loosening and failure of the implant.Large head metal-on-metal total hip arthroplasty may overcome polyethylene wear induced prosthetic failure, but
