摘要(Abstract)：

[目的]测量国人正常胫骨近端截面的线面参数,并与作者自主研发的新型国产膝关节假体胫骨组件(CY-knee)进行涵盖率分析,从而为新型国产人工膝关节假体(CY-knee)的设计提供数据支持。[方法]随机选取健康国人志愿者共120人(210膝),其中男性68例(126膝),女性52例(84膝)。年龄19~81岁,平均45.8岁。通过CT三维重建测量一定截骨高度、一定后倾角度胫骨近端截面的横径及前后径,并利用5 mm容差范围法与新型国人膝关节假体胫骨组件(CY-knee)进行涵盖率研究。[结果]测得胫骨截面横径平均为(75.00±4.87)mm,前后径平均为(51.39±4.06)mm;此种新型国产膝关节假体胫骨组件(CY-knee)对国人全膝关节置换术胫骨平台承受面适配涵盖率平均值为89%。[结论]国人胫骨近端的几何形态与解剖特点同西方人有明显的区别;较目前国内常用进口膝关节假体,此种新型国人胫骨假体组件(CY-knee)涵盖率更高,更适合应用于国人的全膝关节置换术中。
