摘要:

文题释义:
有限元法:是一种基于计算机断层成像数据的移动式立方体算法,通过三维重建后的几何模型转换为有限元网络,使其模型的结构完整、三维空间呈现准确度高、单元划分紧密精准、重点突出,对整体连续型结构转变为离散型,可以反映模型的连续性力学及物理变化参数。
髌腱炎:是膝部常见的软组织损伤之一,目前尚不清楚如何将髌腱炎患者的病理症状减轻及疼痛减小,治疗机制尚不明确,但综合其风险因素以及病理学研究指出其可能是由于膝部相关组织构建结构发生了异常、髌腱过度受力所导致的肌腱发生慢性退行性改变,相比临床上膝部难以区分的其他病变,髌腱炎可能反映的不仅仅是一种炎症。


背景:对于髌腱炎生物力学的研究利用实验条件获取存在一定的难度,有限元法可以利用其强大的建模及模拟计算机功能解决实验获取存在的难题。

目的:总结有限元分析在髌腱炎产生机制、治疗方法、膝部可穿戴设备的设计等几个方面的应用,为髌腱炎的预防及康复提供理论性指导,并对有限元分析在髌腱炎研究的应用提供新的思路。

方法:第一作者以“有限元分析,髌腱(炎),膝部,生物力学,finite element alaysis,Patellar tendinitis,knee,biomechanics”为检索词,在中国期刊全文数据库(CNKI)、SportDiscus、PubMed数据库、Elsevier数据库中检索1981至2019年发表的相关文献。

结果与结论:目前各种用于模拟人体生物力学作用机制的模拟分析算法被不断地开发,进而实现对复杂结构膝部组织及可穿戴设备模型的建立和分析;实现对膝部连续运动状态下非线性的、动态分析,使得模拟分析的真实度得以提升;利用有限元法进一步进行髌腱炎治疗手段的探索、康复器械的研发、可穿戴设备类整体材料和结构的设计,都将是今后研究的发展方向。

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.

Key words: finite element analysis, patellar tendinitis, biomechanics, knee, wearable devices, kinesio taping, organization construction, modeling
