Abstract

In this study, a three dimensionally modeled human hip joint with and without prosthesis was investigated by using finite element method. In scope of the study, 3 different types of cemented prosthesis namely; Charnley, Muller and Hipokrat were used. After preparing the solid models of the hip joint, the models were exported to Ansys Workbench program in order to create 3-D finite element models of the hip joint. The finite element analysis were then pursued for walking and stair climbing activities using concentrated force conditions applied statically. The von-Mises stresses and strains on the cortical and trabecular layers of bone, prosthesis and bone cement were determined at the end of the finite element analysis and compared to each other.
