N2 - Cementless femoral stems have been associated with surface strain changes and stress shielding after total hip arthroplasty. The changes may lead to post-operative bone resorption, micromotion, microfracture or implant failure. Therefore, detailed analysis of femoral surface strain before and after implantation can be useful in determining the features of implant designs that promote strain changes. The purpose of this research is to determine to what affect different cementless stem designs have on the surface strains of the femur. This protocol will follow a technique developed in a pilot study that uses the photoelastic method to resolve the fringe patterns on the femur, commercially available computer software to image these patterns, and original software programs to analyze the surface strains and provide comparative data.
