The finite element method, one of the most advanced simulation techniques in solid mechanics, is used for orthopedic biomechanics. It is used as a tool for the design and analysis of total joint replacement and other orthopedic devices. The design of hip joint prostheses is a complex process that requires close co-operation between engineers and surgeons. To design highly durable prostheses one has to take into account the natural processes occurring in the bone. Hip prosthesis was used for the patients who has the hip fracture and unable to recover naturally. This study aims to analyses the hip prosthesis by finite element analysis. The model is cementless hip stem which were used to analyses simulating common physiological activity standing. The design of a hip prosthesis involves parameters which include femoral neck and femoral head. The results showed that the neck size and femoral head affected by stress distribution on hip prosthesis when inserted in the femoral bone. The maximum von Mises stress at the neck of model and maximum von Mises stress at the head of the model, Total deformation and directional deformation were also analyzed. The von mises stresses were analyzed to find the relationship between the ranges of applied loads. These parameters were taken to rectify old design with the new design in terms of material, shape of the implants without compromising the functionality of the implant and appropriate shape for the titanium implant is proposed. These findings can form a base for further research such as the optimum design of boneimplant hip prosthesis. This study is aimed to analyze the stress and deformation of hip prosthesis by finite element analysis , when inserted in the femoral bone
