人工髋, 膝关节磨损测试标准及模拟试验机研究进展

Hip and Knee joint prosthesis suffers friction and wear in the body, which leads to bone dissolution and aseptic loosening. Hip and Knee joint implants wear test is a major way to evaluate the materials, design and processing of prosthesis. The movement and load of the synovial hip and knee joints are very complicated, so studying the force and range of motion of synovial joints under various behaviors, as well as using the special hip/knee joint simulator for testing and evaluation, is helpful for the design and development of artificial joints and wear-resistant materials. This paper sorts the movement range and load of synovial hip and knee joints, compares the domestic and international wear standards of artificial hip and knee prosthesis, summarizes the structure and main technical parameters of the mainstream hip and knee joint simulator, and provides a reference to studies in the artificial joint industry in China.
