Abstract: BACKGROUND: Knee joint testing machine research can improve the performance of knee joint prosthesis, provide guarantee for clinical replacement surgery, and increase the success rate of surgery.
OBJECTIVE: To analyze the current status of research on knee joint testing machine at home and abroad, explore the shortcomings of the testing machine at present and the research direction of knee testing machine in the future.
METHODS: The computer searched CNKI, Wanfang, ScienceDirect and other domestic and foreign databases. The Chinese and English keywords were “knee replacement, joint testing machine, knee testing machine”.
RESULTS AND CONCLUSION: The research level of domestic knee joint testing machines is not high, and most of the testing machines are imported from abroad. The research of domestic scholars on knee testing machine is still in the ability to simulate the motion condition of knee prosthesis in human body, and it is only the simulation of motion condition, while the foreign research has entered a deeper level. In terms of wear test standards, due to the late start of domestic research, there is still a lack of test standards suitable for Asian sports, and there are deficiencies in the quantification of daily mechanical movements. Combining the needs of real experiments and the characteristics of the human body, the research of the knee testing machine should increase research efforts in several aspects such as the fidelity of the test environment, the similarity of the geometric shape of the prosthesis, and the influence of the involved motion.
