摘　　要：目的:建立膝关节半月板三维有限元模型。方法:拍摄健康成人膝关节CT图像,使用Materialise Interactive Medical ImageControl System 10.0(Mimics10.0)、Freeform Modeling System 10(FMS10)、ANSYS12.0等软件建立半月板三维有限元模型并进行初步生物力学分析验证模型的有效性。结果:建立的半月板三维有限元模型几何形态与实体解剖标本相似性高。初步生物力学分析结果显示模型能准确反映半月板的生物力学特性。结论:采用CT扫描图像建立膝关节半月板三维有限元模型是切实可行的。Objective：To establish the three-dimensional finite element model of the menisci.Methods：Knee joint of a healthy adult was used as specimen.CT scan images and Materialise Interactive Medical Image Control System 10.0（Mimics10.0）、Freeform Modeling System10（FMS10）,ANSYS12.0 were used to build the three-dimensional finite model of menisci.And the model was used to analyze the biomechanics of the menisci to verify the validity of the model.Results：An three-dimensional finite element model of menisci was established successfully,and the model provides a precise anatomic morphology of the menisci.The finite element analysis of the model demonstrated that could reflect the biomechanics of the menisci approximately.Conclusion：It is practical to build Menisci three-dimensional finite element models with CT scan images.
