Finite element analysis on the biomechanical changes of patellar tendinitis / 中国组织工程研究

ABSTRACT

BACKGROUND: It is difficult to obtain the biomechanics of patellar tendinitis by using experimental conditions. Finite element method can solve this problem by using its powerful modeling and computer simulation functions. OBJECTIVE: To summarize the application of finite element analysis in several aspects, such as the mechanism of patellar tendinitis, treatment method and design of knee wearable device, so as to provide theoretical guidance for the prevention and rehabilitation of patellar tendinitis, and provide new ideas for the application of finite element analysis in the study of patellar tendinitis. METHODS: The first author used the search terms “finite element analysis, patellar tendon (patellar tendinitis), knee, biomechanics” in Chinese and English, respectively. Relevant literature published from 1981 to 2019 in CNKI, SportDiscus, PubMed and Elsevier databases were searched. RESULTS AND CONCLUSION: At present, a variety of simulation and analysis algorithms for simulating the mechanism of human biomechanics are continuously developed, so as to establish and analyze the knee tissue with complex structure and the wearable device model. The nonlinear and dynamic analysis of the continuous motion of the knee will be realized, and the simulation analysis will be more real. Further exploration of the treatment of patellar tendinitis by using finite element method, research and development of rehabilitation equipment, and design of overall materials and structures of wearable devices will be the development direction of future research.
