Many factors contribute to failure of a hip arthroplasty. These include infection, instability, fracture and loosening of implants, and malalignment of the artificial joint component. Recently, many clinical reports have demonstrated that osteolysis and aseptic loosening are associated with wear debris from the articulating surface [7,13,14,17,19]. Therefore, research over the past several decades have focused on the reduction of the particle debris. For example, many types of materials have been used as artificial joint components. However, little information is available concerning the stress distribution pattern and the micromotion of the proximal femur and the femoral stem associated with the use of these materials in total hip arthroplasty. Therefore, the purpose of this study is to evaluate the effect of three different articulating materials used in total hip arthroplasty on the stress and micromotion of the proximal femur and femoral stem.
