With the increase of life expectancy of the aging population and more and more young patients need surgical treatment of arthritis, there is an urgent need to improve the durability and clinical life expectancy of artificial hip joint. In this study, the range of motion (ROM), tribological performance and mechanical properties of artificial hip joints of different sizes were studied and compared by means of finite element analysis and computer aided design. We found that the larger femoral head has greater ROM and better mechanical properties. However, a larger head can cause serious wear problems, which can lead to aseptic loosening. Considering these three factors, a systematic analysis method of artificial hip joints is set up, and the range of 38 mm to 42 mm is believed to have better performance. In future work, more detailed factors, such as lubrication conditions, need to be considered in order to get a more accurate analysis.
