半月板有限元分析的研究进展

对半月板生物力学研究一直是医学科研热点之一。有限元分析法(FEA)提供了一种新的思路和方法。通过建立半月板有限元模型,利用软件分析可获得正常半月板的应力应变分布特点,也可模拟半月板撕裂、半月板切除、以及膝关节各组织损伤,研究半月板力学特性的改变,为临床疾病的预防治疗以及康复提供理论力学依据。但目前的有限元分析法存在其局限性,未来建立高质量的有限元模型,使模型更真实反应半月板的解剖特点,以及将有限元分析法运用到更多的膝关节损伤中应是研究的方向。

Progress in finite element analysis of meniscus

The meniscus biomechanics is one of the hottest areas in medical research. Finite element analysis(FEA) provides a new method for biomechanical studies. Using the FEA,the stress force and strain distribution characteristics of the normal meniscus can be analysed by establishing the finite element model of the meniscus and utilizing finite element softwares. In addition,the finite simulation of the meniscus tears,meniscectomy,and knee tissue injury can assess the changes of meniscus biomechanical properties. These research results provide theoretical basis of biomechanics to prevent and treat knee joint injuries. However,the finite element analysis method has its limitations,future research will be aimed at establishing high quality finite element models,making the models offer more authentic simulations of the meniscus anatomy,and ensuring the FEA could be applied to research a variety of knee injuries.
