[Development of hip joint simulators].
Currently, hip replacement is an effective treatment for some hip joint diseases. The friction and wear of a prothesis in the human body are the main causes for the failure of joint arthroplasty. It is, therefore, very important to simulate the working conditions of a hip prosthesis in order to get an optimal design and successful clinical applications. This article summarizes wear testing methods of hip prostheses and the developing status of their simulators. Three key aspects of the simulators, i.e., the structures, motions and lubrications, are analyzed in detail. At the end, the developing trend of the simulators are discussed.
