Abstract: BACKGROUND: Finite element analysis has been widely used in the knee joint due to its visualization and noninvasion. International research in this field has been increasing year by year, and the finite element analysis model has achieved fruitful results and gradually diversified. However, less is reported on the research status, hot spots and trends of finite element analysis of the knee joint.
OBJECTIVE: To analyze the current research status, hot spots and trends of finite element technology used in the knee joint in recent 10 years using visual analysis method.
METHODS: The core collection of Web of Science was used as the data source to search for relevant literature on the subject of finite element analysis and knee joints from 2011 to 2020. CiteSpace.5.7.R2 software was used to conduct scientific knowledge map analysis and literature review on the research related to the application of finite element technology in the knee joint. 
RESULTS AND CONCLUSION: After deduplication, a total of 1 026 articles were included. In the past 10 years, the number of published papers and citation  frequency in this field has increased year by year, with a total of 11 088 citations. A total of 256 journals have published articles related to this field. The research fields of the included journals are concentrated in biophysics, engineering, computer science, and orthopedic surgery. JOURNAL OF BIOMECHANICS published the most papers in this field. A total of 328 institutions and 342 authors from 62 countries have published related studies. The top three countries with the most publications are the United States, China, and England in sequence. The top three institutions with the most publications are Yonsei University and Yonsei Sarang Hospital in South Korea, and the University of Eastern Finland. Professor Kyoungtak Kang’s team has the largest number of publications. Key word analysis shows that the finite element analysis in knee joint research mainly focuses on articular cartilage, osteoarthritis, knee replacement, meniscus resection, biomechanics, component research, etc. In the past 4 years, knee revision, unicompartmental knee arthroplasty, and malalignment have become frontier issues. The research direction has gradually developed from the initial experimental research to the clinical decision-oriented research in the past 10 years. The research content has shifted from the establishment, optimization, and verification of models to the exploration of surgical prostheses, surgical approaches, and repair materials. Research on the development of materials/prosthesis performance, auxiliary knee arthroplasty/implantation and other repair technologies will become the future development trend in this field.

Key words: finite element analysis, finite element model, knee joint, citespace, visual analysis, biomechanics, replacement, revision
