摘　　要：目的:对华南地区人群实施Oxford第3代UKA假体进行临床研究,为进一步实施单髁置换术准确判断假体大小,选择合适的单髁假体提供参考。方法:回顾性分析2015年3月至2017年11月开展的276例单髁置换术人群的相关临床资料。统计分析276例患UKA假体型号的具体尺寸分布(股骨、胫骨),记录该人群的性别、年龄、左/右侧、体质量、身高及BMI指数,统计分析股骨假体型号与上述因素的相关性;分析股骨与胫骨假体的最佳匹配关系,筛选出华南地区人群UKA假体的影响因素,统计分析预测股骨假体型号的准确度。结果:1)股骨假体型号分布,XS为31.16%,S为51.81%,M为15.94%,L为1.09%,XL为0%.2)胫骨假体型号分布,AA为27.17%,A为26.09%,B为28.26%,C为14.49%,D为3.99%,E为0%,F为0%.3)股骨与胫骨假体的最佳匹配情况:胫骨AA匹配股骨XS,胫骨A、胫骨B匹配股骨S,胫骨C和D匹配股骨M.4)相关性分析:年龄、部位和BMI对股骨假体大小选择的影响差异无统计学意义(P>0.05),而性别(P<0.01)和身高(男性,P<0.01;女性,P<0.01)两个因素差异有统计学意义。5)建立华南地区人群UKA假体相关参数的分布图。按本研究结果,采用性别结合身高这两因素判断股骨假体型号的准确性,女性患者达到95.9%,男性患者达到75.3%;而在采用胫骨假体大小判断股骨假体大小的准确性达到63.0%.结论:华南地区人群UKA假体分布情况不同于欧美人群,华南地区人群UKA假体分布图有较高的预测准确度,能指导术中选用大小合适的股骨假体。Objective：To study the prosthesis size of unicompartmental knee arthroplasty（Oxford 3 rd UKA）in Southern China population so as to provide a good reference for selecting appropriate UKA prosthesis.Methods：From March 2015 to November 2017,276 Oxford phaseⅢ UKA cases of Southern China patients were retrospectively studied.The clinical data of 276 patients with single condylar replacement were analyzed retrospectively from summary description of the size of the UKA prosthesis（femur,tibia）.The optimal matching relationship between femur and tibial prosthesis was analyzed.Correlation analysis was conducted between prosthesis size and the following factors such as gender,age,left/right side,weight,height and BMI index.The influencing factors of UKA prosthesis in southern China population were screened,and the accuracy of predicting femoral prosthesis size was statistically analyzed.Results：1）Size distribution of femoral prosthesis was XS 31.16%,S 51.81%,M 15.94%,L 1.09%and XL 0%.2）The size distribution of tibia prosthesis was AA 27.17%,A 26.09%,B 28.26%,C 14.49%,D 3.99%,E 0%and F 0%.3）The best match of the prosthesis was as follows：tibia AA with femur XS,tibia A and B with femoral S,tibia C and D with femoral M.4）Correlation analysis：age,location and BMI had no significant influence on the size selection of femoral prosthesis.Gender（P〈0.01）and height（male,P〈0.01;female,P〈0.01）have statistical significance.5）The distribution of the related parameters of the UKA prosthesis in south China population was preliminarily established.The accuracy of femur prosthesis size judged by gender and height was 95.9% in female patients and 75.3%in male patients,while it was 63.0 % of tibia prosthesis.Conclusion：The distribution of the UKA prosthesis in south China population is different from that of the European and American groups.The map of the UKA prosthesis in south China has high prediction accuracy and can guide the selection of femoral prosthesis with appropriate size.
