Abstract
The simulator testing in vitro and computational simulation of the artificial knee joint wear are important methods to evaluate the wear performance of the prosthesis in vitro and to predict the clinical performance of knee joint products. Based on the method of literature search, this paper compares the mechanical and kinematic loading input curves carried out by Chinese scholars in recent years, standard curves, and Chinese measurement curves of two typical movements of gait. Data of vitro simulator test and computational simulation model are compared, summarized, and analyzed. The results show that the measured data of motion and load cannot be directly used as the loading conditions for the simulator wear test and computational simulation. The mechanics and kinematics data of Chinese people are different from the international standards. The domestic artificial knee joint in vitro simulator wear test methods are similar but the results of different test institutions are somewhat different. The computation wear prediction research is basically synchronized with foreign countries, but the problem that the calculated wear results are lower than that in vitro test is still unsolved. The artificial knee joint wear performance evaluation system based on Chinese knee joint mechanics and kinematics data is the forward direction of the research.
