摘要
目的:探讨膝胫股关节软骨损伤与膝关节股骨角、胫骨角、股骨胫骨角及关节间隙角的相关性。方法:回顾性分析2017年1月至2017年6月于承德医学院附属医院南院区进行膝关节MRI检查的患者587例,通过纳入标准及排除标准随机选取病例组及对照组各100例。分别测量两组人群的股骨角、胫骨角、股骨胫骨角及关节间隙角,并利用SPSS19.0对相关角度数据进行统计分析,统计方法包括秩和检验、Spearman相关性检验及ROC曲线。结果:病例组股骨角、胫骨角、股骨胫骨角及关节间隙角分别为83.22(81.85～84.40)°、95.60(94.10～96.87)°、179.00(177.50～180.25)°及1.92(1.43～2.43)°,对照组股骨角、胫骨角、股骨胫骨角及关节间隙角分别为82.50(81.70～83.60)°、94.25(93.20～95.52)°、177.20(175.90～178.17)°及0.58(0.50～0.95)°。两组胫骨角、股骨胫骨角及关节间隙角差异有统计学意义(P <0.05),股骨角差异无统计学意义(P> 0.05);软骨损伤程度与关节间隙角呈显著正相关(rs=0.852,P <0.001),与胫骨角及股骨胫骨角无显著相关性。胫骨角的最佳临界值、敏感性及特异性分别为95.15°、56%、72%;股骨胫骨角的最佳临界值、敏感性及特异性分别为179.05°、49%、92%;关节间隙角的最佳临界值、敏感性及特异性分别为1.255°、84%、96%。结论:胫骨角、股骨胫骨角及关节间隙角的增大会影响膝胫股关节软骨,导致其损伤;且随关节间隙角的增大,膝胫股关节软骨损伤程度加重。
Objective:To investigate the relationship between cartilage injury of knee tibiofemoral and femoral angle,tibial angle,femorotibial angle and joint space angle of knee joint.Methods:A retrospective analysis was made of 587 patients who underwent knee joint MRI examination in the Southern Hospital of Chengde Medical College from January 2017 to June 2017.100 patients in the case group and 100 patients in the control group were randomly selected through inclusion and exclusion criteria.The femoral angle,tibial angle,femorotibial angle and joint space angle were measured in two groups,and the correlation angle data were statistically analyzed by SPSS 19.0.The statistical methods included rank sum test,Spearman correlation test and ROC curve.Results:The femur angle,tibial angle,femorotibial angle and joint space angle of the case group were 83.22(81.85 to 84.40) degrees,95.60(94.10 to 96.87) degrees,179(177.50 to 180.25) degrees and 1.92(1.43 to 2.43) degrees,respectively.The femoral angle,tibial angle,femur tibial angle and joint clearance angle of the control group were 82.50(81.70 to 83.60) degrees,94.25(93.20 to 95.52) degrees,177.20(175.90 to 178.17) degrees and 175.90(0.50 to 0.95) degrees.There were significant differences in tibial angle,femorotibial angle and joint space angle between the two groups(P < 0.05),but there was no significant difference in femoral angle(P > 0.05),cartilage injury was positively correlated with the joint space angle(rs= 0.852,P < 0.001),but not with tibial angle and femorotibial angle.The optimal threshold value,sensitivity and specificity of tibial angle were 95.15 degrees,56% and 72%,respectively.The optimum critical value,sensitivity and specificity of femorotibial angle were 179.05 degrees,49% and 92% respectively,and the optimum critical value,sensitivity and specificity of joint space angle were 1.255 degrees,84% and 96%,respectively.Conclusion:The increase of tibial angle,femorotibial angle and joint space angle will affect the tibiofemoral joint cartilage and lead to the i
