摘要：

背景：在进行中国人膝关节假体设计以及全膝关节置换时，不仅要考虑到中国人胫骨近端解剖特点和几何形态上的差异，同时也还应该注意不同个体间的差异性。
目的：通过数字化技术分析中国人正常胫骨近端正常形态学参考值的变化。
方法：采集正常中国人两侧膝关节原始CT扫描图像，Mimics 10.1软件系统构建膝关节骨三维数字化模型。并对胫骨近端模型模拟截骨，测量胫骨截面相关线性参数。根据不同性别进行分组观察胫骨近端形态学参考值的变化。
结果与结论：除胫骨平台外侧前后径/内侧前后径、内侧前后径与外侧前后径的差值外，男性横径和前后径值均大于女性，大部分男性受试者所测量胫骨近端各截骨面值与女性受试者相比差异有显著性意义(P < 0.01)。说明正常中国人胫骨近端形态学存在性别个体差异，具体表现在：①不同测量方法形成的测量数据可更加全面反映胫骨近端形态学特征。②胫骨平台前后径/胫骨平台横径比值方面女性大于男性。

Abstract:

BACKGROUND: During China knee prosthesis design and total knee replacement, not only the anatomical characteristics of the proximal tibia of the Chinese population and the differences in geometry should be considered, but also should pay attention to the differences between the different individuals.
OBJECTIVE: To analyze the changes of morphology reference value of normal proximal tibia of the Chinese population by digital technology.
METHODS: We collected the original CT scan images of knee joints in both sides of the Chinese population, and the three-dimensional digital model of knee joint was established with Mimics 10.1 software. The simulation osteotomy of proximal tibial model was performed and the relevant linear parameters of tibia section were measured.
RESULTS AND CONCLUSION: In addition to the anteroposterior diameter of the lateral tibial plateau/anteroposterior diameter of the medial tibial plateau and the difference between anteroposterior diameter of the lateral tibial plateau and anteroposterior diameter of the medial tibiale plateau, the transverse diameter and anteroposterior diameter of male patients were bigger than those of the female patients, there was significant difference of proximal tibial osteotomy nominal value between most of the male patients and female patients (P < 0.01). With the increasing of body mass index, the anteroposterior diameter of the medial tibial plateau and the transverse diameter of the tibial plateau were also increased. It indicates that there is difference among the proximal tibia morphology of normal Chinese people in gender and body mass index, reflecting in: ①The data measured by different measurement methods can fully reflect the morphological characteristics of the proximal tibia. ②The ration of anteroposterior diameter of the tibial plateau /transverse diameter of the tibial plateau of female patients is higher than that of the male patients.
