文题释义：
胫骨平台后倾角：是人工膝关节置换术中的重要截骨参数，胫骨平台后倾角的测量有多种参照标准，也可以通过不同途径测量，一般以胫骨前皮质线、胫骨中轴线和胫骨后皮质线为纵轴线，胫骨平台前后缘连线与轴线的垂线所成的角度为胫骨平台的后倾角。
膝关节置换：是将膝关节表面退变和增生的软骨及骨组织去除，以金属关节代替，以减轻患者疼痛和重建功能为目的，主要适用于骨性关节炎、类风湿性关节炎和创伤性关节炎等。目前的膝关节置换又称表面膝关节置换，因为手术切除的部分为膝关节表面磨损的软骨及少量的骨组织。
 
摘要
背景：目前国内及国外膝关节的测量较多，但是关于北方局部地区尤其内蒙古地区的测量较少，局部地区胫骨平台后倾角与国人甚至国外人种的数据是否有差异目前研究较少。
目的：测量蒙古族人正常膝关节胫骨内侧平台后倾角的大小，比较不同测量方法间的差异，以期得到蒙古族正常原始的胫骨内侧平台后倾角数据。
方法：GE64排螺旋CT扫描60名蒙古族志愿者双膝关节的胫骨上段和股骨下段各20 cm，连续水平扫描获得数据，Mimics 16.0建立膝关节三维模型，模型经光顺、填充、分离、切割等处理，在切割后模型断面上，测量胫骨中上段前侧骨皮质延长线(A方法)，胫骨骨干解剖轴(B方法)，胫骨后侧骨皮质延长线的垂线(C方法)和胫骨平台上缘线的交角，得到不同测量方法的后倾角值(90°减去测得的角度)。
结果与结论：①A方法测得的胫骨平台后倾角为(11.16±3.39)°，B方法为(8.60±3.29)°，C方法为(5.30±4.40)°，其中A、B方法测得结果与王业华及罗吉伟报道的数据相近(P > 0.05)；②A，B，C方法测量所得的左侧胫骨平台后倾角度比较，差异有显著性意义(P < 0.05)，A，B，C方法测量所得的右侧胫骨平台后倾角度比较，差异亦有显著性意义(P < 0.05)；但左右侧别之间差异无显著性意义(P > 0.05)；③左侧、右侧胫骨平台后倾角度分别在不同性别间比较，差异均无显著性意义(P > 0.05)；④结果提示，蒙古族人膝关节胫骨内侧平台后倾角较小，A、B方法测得的结果与王业华及罗吉伟报道的数据近似，但胫骨平台后倾角个体差异较大，术中截骨应根据个体情况来决定。

Abstract:

BACKGROUND: There are more measurement data about knee joint at home and abroad, but few data about the northern China, especially Inner Mongolia region. Whether the posterior slope angle of tibial plateau in local area differs from that of Chinese or foreigners is rarely reported.

OBJECTIVE: To measure the posterior slope angle of the medial tibial plateau in healthy Mongolia population, and to compare the differences of different measurement methods, so as to understand the anatomical characters of tibial plateau in Inner Mongolia region.
METHODS: Sixty Mongolian volunteers were recruited, the 20 cm upper and under the knee joint were scanned bilaterally by GE64 row spiral CT, and the three-dimensional model of the knee was established on Mimics16.0 software, followed by processed through fairing, filling, separation and cutting. Afterwards, the angel between anterior cortical bone extension line of upper tibia (method A), tibia anatomical axis (method B), line perpendicular to the posterior cortical bone extension line of upper tibia (method C) and upper edge line of the tibial plateau was measured, respectively. The posterior slope angle of the medial tibial plateau (90°-measured angle) was obtained and compared.
RESULTS AND CONCLUSION: (1) The posterior slope angle of the medial tibial plateau measured by methods A, B and C was (11.16±3.39)°, (8.60±3.29)° and (5.30±4.40)°, respectively, and the former two were similar with those reported by Wang Ye-hua and Luo Ji-wei (P > 0.05). (2) There were significant differences in the posterior slope angle of the left and right medial tibial plateau among methods (P < 0.05), but there was no significant difference between left and right sides (P > 0.05). (3) There was no significant difference in the posterior slope angle of the left and right medial tibial plateau between genders (P > 0.05). (4) These results indicate that the Mongolian population show smaller posterior slope angle of the tibial plateau, but the angle exhibits great individual difference, thereafter, an individualize scheme should be developed before osteotomy.
