BACKGROUND： It is difficult to study the biomechanics of plantar fasciitis under the present experimental conditions. Finite element method can solve these problems with its excellent modeling and simulation functions. OBJECTIVE： To investigate the application of finite element analysis in the pathogenesis of plantar fasciitis, the treatment method, the design of shoes and insole, so as to provide theoretical guidance for the prevention and rehabilitation of plantar fasciitis, and provide a new idea for the application of finite element analysis in plantar fasciitis research. METHODS： The first author retrieved CNKI, Baidu Xueshu and Pub Med databases for the articles published from 1981 to 2016 using the keywords of ＂finite element analysis, plantar fascian（fasciitis）, foot, biomechanics＂ in Chinese and English, respectively. RESULTS AND CONCLUSION： With the development of computer technique, the finite element method is used to analyze the mechanical response of plantar fascia and study the mechanical mechanism of foot internal structure, providing theoretical guidance and suggestion for revealing the mechanism of plantar fasciitis and related treatments. Importantly, the finite element method achieves the non-linear and dynamic analysis of the foot, so enhance the authenticity. In addition, the use of the finite element method to further explore the treatment of plantar fascitis, the development of rehabilitation equipment, and the design of the overall structure of footwear will be the direction of future research.
