摘要：

背景：近年来有关膝关节前交叉韧带三维数字化模型的研究在国外发展迅速，但在国内，未见对包括全膝关节及前交叉韧带在内的三维数字化模型进行基础解剖研究的报道。
目的：评估运用MRI二维图像及MIMICS软件建立膝关节及前交叉韧带三维数字化模型的真实性及可靠性。
方法：选择20例新鲜成人尸体正常膝关节标本，利用MRI对标本进行二维扫描，获得层厚为1.0 mm的连续图像资料，将该资料以DICOM格式导入计算机并利用MIMICS软件进行三维重建，建立包括股骨远端、胫骨近端、前交叉韧带、半月板、髌骨及腓骨等在内的双膝关节三维实体数字化模型，利用测量软件测量相关指标；同时对尸体标本进行解剖并测量膝关节前交叉韧带的相关参数，与模型所测指标行配对比较。
结果与结论：尸体标本测量数据与三维实体数字化模型测量数据的结果差异均无显著性意义(P > 0.05)。提示利用MRI采集获得的人体膝关节及前叉韧带图像数据可以建立较为真实可靠的膝关节及前交叉韧带三维实体数字化模型。

Abstract:

BACKGROUND: In recent years, the research about three-dimensional digital models of anterior cruciate ligament has been developed rapidly in abroad. However, there is no basic anatomy report about three-dimensional digital models of the knee joint and anterior cruciate ligament at home.
OBJECTIVE: To explore the validity and reliability of two-dimensional MRI image and MIMICS software in building three-dimensional digital models of the knee joint and anterior cruciate ligament.
METHODS: Twenty fresh normal adult corpse knee-joint specimens were selected, then they were scanned with MRI, acquired continuous image data of level thick 1.0 mm, and these data were imported into computer with DICOM form and were carried through three-dimensional reconstruction by using MIMICS software. The three-dimensional substance digital models of double knee joints which included femur distal end, tibia proximalis, anterior cruciate ligament, meniscus, patella and fibula were reconstructed. Measurement software was utilized for relevant indexes. Meanwhile, the corpse specimens were dissected to measure relevant data of the anterior cruciate ligament, and the difference of measured indexes between the corpse specimen and the three-dimensional substance model was analyzed.
RESULTS AND CONCLUION: There was no difference between the data of corpse specimen and three-dimensional substance digital model (P > 0.05). It indicated that MRI image data of the human knee joint and anterior cruciate ligament could be used to reconstruct the authentic and reliable three-dimensional digital models of the knee joint and anterior cruciate ligament.
