Popis:	Considering effects of physiological factors in failure of total hip arthroplasty, a numerical procedure was implemented for the three-dimesional (3D) shape optimization of femoral component of total hip replacements on the basis of remodeling objective functions. Design variables are the shape parameters, which define the femoral component geometry. The 3D design model was incorporated with 3D finite element analysis and a numerical optimization procedure. The main optimization goal was to reduce the potential for change of the bone morphology and to keep it close to the normal condition of an intact femur, by changing the geometry of the implant. Both local and global remodeling goals were examined. The results suggest a much more slender implant than is normally used would be required to minimize the remodeling potential. The results also demonstrated that the outcomes are indeed sensitive to whether the remodeling goal is treated as local or global.
