In this study, a three dimensionally modeled human hip joint was investigated by using finite element method. During this study, finite element models were prepared for three different prosthesis types namely; Charnley, Muller and Hipokrat and for two different activities as walking and stair climbing motions. Ansys Workbench commercial program was used for finite element analysis by applying distributed load condition. The von- Mises stresses and strains occurred on the cortical and trabecular layers of bone, prosthesis and bone cement which was used to assemble prosthesis into bone's intramedullary canal, were determined at the end of the finite element analysis and compared to each other.
