Abstract
Hip joint is the primary joint which provides stability to the human body. Ageing of human, disease and accidental circumstances are the focal point for hip replacement surgery. Hip Arthroplasty is a surgical procedure for replacing the disease or fractured hip joint. Present analysis consists of Charnley’s femoral stem with three metallic materials i.e. CoCrMo, Ti-6Al-4 V and Ti-6Al-7Nb, undergoing to the realistic dynamic loading i.e. average walking load condition. These three materials demonstrate excellent biocompatibility. The aim of this paper is to analyze the mechanical parameters i.e. stress, deformation and strain of the femoral stem for walking, based on in vivo loading conditions obtained from patient’s practical activities, in order to find out the most suitable implant material. The final outcome demonstrates that CoCrMo is the best suited material because this metallic material demonstrates maximum stress with minimum deformation and strain as compared to other two.
