膝关节有限元分析的研究热点及趋势

Finite element analysis of the knee joint:research hotspots and trends

背景:有限元分析以其可视化、无创性等特点在膝关节中的应用日益广泛,国际上对该领域的研究逐年递增,有限元模型成果丰硕,且逐渐多元化。但对于膝关节有限元分析的研究现状、热点、趋势较为缺乏。目的:利用可视化分析方法探索近10年有限元技术应用于膝关节的研究现状、热点及趋势。方法:以Web of Science核心合集为数据来源,检索2011-2020年以有限元分析与膝关节为主题的相关文献,运用citespace5.7.R2软件对有限元分析在膝关节应用的相关研究进行科学知识图谱分析和文献梳理。结果与结论:①去重后共纳入1026篇文献,近10年该领域发文量及被引频次逐年增长,被引频次总计达11088次。②共256种期刊发表了该领域相关文章,收录期刊研究领域集中于生物物理学、工程学、计算机科学、矫形外科学,其中发文量最高的期刊为《JOURNAL OF BIOMECHANICS》。③共有62个国家、328个机构、342个作者发表该领域的相关研究,发文数量排名前3的国家依次是美国、中国、英格兰;发文量前3个机构为韩国的延世大学、韩国延世Sarang医院、东芬兰大学,其中KYOUNGTAK KANG教授团队发文量最多。④关键词分析表明,有限元分析在膝关节应用研究内容主要集中在关节软骨、骨关节炎、膝关节置换、半月板切除、生物力学及组件研究等方面,近4年来膝关节损伤修复、单髁置换、轴线不对称等方向成为研究前沿。⑤膝关节有限元分析的相关研究方向在10年来由最初的基础实验研究,逐渐向以临床决策为导向的科研角度发展,研究内容从模型的建立、优化和验证等方面转向对手术假体、入路及修复材料等方面的研究,而对材料/假体性能、辅助膝关节置换/移植等修复技术发展的研究将成为该领域今后的发展趋势。

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 1026 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 11088 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.
