BACKGROUND: Parametric design of knee prosthesis is an effective method to reduce the loss of prosthesis and improve the survival rate of prosthesis. However, there is still a lack of comprehensive analysis on the parameterization of knee prosthesis. OBJECTIVE: To summarize the failure forms of total knee arthroplasty, the research progress of parametric design of knee prosthesis, and put forward some suggestions. METHODS: Using the terms “TKA, Knee prosthesis, Tibial liner, Parametric design, Prosthesis replacement, Prosthesis loosening, Failure mode, Durability, Kinematics” as Chinese and English key words, relevant articles were searched in PubMed, Embase, CNKI, Wanfang and VIP databases. Finally, 64 articles were included. The development of knee prosthesis from three aspects was summarized and analyzed: Failure form of artificial knee joint prosthesis; development of parametric design of knee prosthesis; perfecting the parametric design of knee prosthesis. RESULTS AND CONCLUSION: (1) Aseptic loosening, prosthesis infection, instability and tibial pad wear are the main failure forms of knee prosthesis. The knee prosthesis should be retained for several years after implantation. The damage of knee prosthesis, bone loss and the destruction of the original knee balance will have adverse effects on the recovery of the disease and human health. Therefore, we should pay attention to the removal of diseased knee joint and the implantation of prosthesis. Once an accident occurs before and after treatment, it should be diagnosed and treated according to the condition as soon as possible to prevent accidents. (2) The parametric design of prosthesis should make it have better biocompatibility, good contact performance, stable kinematic characteristics and low friction, so that patients can get better rehabilitation effect. (3) The contact mechanical and kinematic properties of knee prosthesis are affected by the consistency of coronal and sagittal curvature radii, respectively. The change of parameters will inevitably lead to the change of performance, so the competition between the kinematic performance and contact mechanical performance of knee prosthesis is inevitable. In the parametric design of knee prosthesis, both should be controlled within a reasonable range. (4) Fitness is an important index in the parametric design of prosthesis, and the division of its high and low levels has not yet been realized, which will be an important problem that scholars should overcome in the parametric design. (5) The research on the parameterization of knee prosthesis can improve its contact performance, make it have more stable kinematic characteristics, and provide important theoretical basis for the production, development and clinical application of prosthesis. It is of great significance to improve the success rate of knee prosthesis replacement, reduce the revision rate of knee prosthesis, and improve the quality of life of patients.
