Abstract

The first purpose of this thesis was to compare the amount of micromotion seen in the femoral stem in a revision total hip arthroplasty between simple loading conditions and loading conditions derived from activities of daily living, through the use of experimental and computational methods. The amount of micromotion at the bone-implant interface was larger for activities of daily living, with ranges of 200μm more than the largest simple loading conditions. The second purpose of this thesis was to compare measurements of accuracy in a statistical shape model between individual bone and joint-level models, specifically for the knee. Using computational methods, this study suggested that individual bone models produced lower amounts of errors in accuracy measurements than joint-level models, specifically when looking at similar number of modes of variation in each model. These two studies present research in the development of the next generation of implants in total joint arthroplasties.
