有限元分析在前交叉韧带运动损伤研究中的研究进展

Progress in finite element analysis of sports injury to anterior cruciate ligament

前交叉韧带(ACL)是膝关节中最容易损伤的韧带,一直是运动医学研究的热点。由于膝关节解剖结构和运动机制十分复杂,对其进行生物力学研究常常难以精确实现。有限元分析可以有效评估多种变量,如移植物类型、手术设计及材料性质等,以预测损伤机制、优化手术技术,弥补了生物力学实验研究的不足,是评估ACL力学行为的重要工具。本文对膝关节ACL运动损伤相关的有限元分析研究和有限元仿真模拟膝关节屈伸运动进行综述,探讨有限元分析在临床应用中的实际意义,以期进一步提高临床医生对ACL运动损伤与修复的认识。

Of all the knee ligaments,anterior cruciate ligament(ACL)is the most likely injured and thus a hot spot in sports medicine research.Complexity of the anatomical structures and motion mechanisms of the knee joint poses a great challenge to the study into the accurate biomechanics of the knee.As finite element analysis can evaluate a variety of variables effectively,such as graft type,surgical design and material properties,it can predict injury mechanisms,optimize surgical techniques and makes up for the deficiencies of biomechanical experiments.It is an important tool to evaluate the mechanical behavior of ACL.This paper summarizes the research progress in finite element analysis of ACL sports injury,discusses its significance in clinical application,and points out the insufficiencies of finite element analysis in simulating knee joint flexion-extension activity.This review may help clinicians to make better use of finite element simulation in the research of ACL sports injury.
