In the prostheses technology, the development of hip joint materials for hip replacement in human body is probably one of the most challenging problems. Even the history of hip arthroplasty is over 100 years; we still have encountered enormous challenge, mainly deal with the quality of the prosthetic materials. Many different material experiments and surgical approaches have been taken around the world to improve the performance of the prosthesis.
The purpose of this document is to investigate the failure of the hip replacement and the total hip replacement in particular. It also provides the failure analysis and methodology as well as exploring the design specification and material selections of human hip replacement prosthesis
