摘　　要：背景:三维图像重建是开展膝关节虚拟研究的基础。关节周围韧带、软骨、半月板等结构分割重建报道较少。目的:在前期大量膝关节标本解剖研究的基础上,利用CT及MRI数据,三维重建包括关节周围韧带、软骨、半月板等结构在内的膝关节模型。方法:采用1例人体成年膝关节标本CT、MRI薄层扫描数据,导入Mimics 10.01分别三维重建膝关节骨、软骨、韧带及半月板等结构,利用逆向工程软件Geomagic 8进行及图像配准处理。结果与结论:三维重建了包括关节周围韧带、软骨、半月板等结构在内的膝关节模型,为建立相应膝关节有限元模型奠定了基础。BACKGROUND：Three-dimensional reconstruction is a foundation of knee joint stimulation.There are few reports regarding structural subdivision and reconstruction of ligament surrounding joint,cartilage,and meniscus.OBJECTIVE：To reconstruct a 3D knee model with ligments,cartilage and meniscus based on previous knee joint anatomy using CT and MRI data.METHODS：CT and MRI data of 1 adult knee joint were harvested and import in Mimics10.1 to reconstruct the structures such as bone,atricular cartilage,meniscus and ligaments of knee joint.The registration was performed with reverse-engineering software Geomagic 8.RESULTS AND COCNLUSION：3D knee joint model with bone,meniscus,ligaments and articular cartilage was reconstructed,which lays a foundation for finite element analysis of corresponding knee joint.
