中文摘要:
目的：用ROC曲线确定Blumensaat角对于诊断前交叉韧带损伤诊断的最佳临界值，以期对Blumensaat角应用于前交叉韧带损伤诊断的价值进行客观评价。
方法：筛选2015年1月至2016年1月间做过膝关节镜检的患者167例，对研究对象的年龄、性别、患肢左右情况分别记录。调取MRI图像，分别测得各对象Blumensaat角，将研究对象分为两组：A组为Blumensaat角≤ 0°的研究对象，B组为Blumensaat角>0°的研究对象。将B组的统计数据绘制ROC曲线，得出当Blumensaat角>0°时，诊断前交叉韧带损伤的最佳临界值。而后根据ROC曲线所得最佳临界值，求得总样本的符合率。
结果：研究对象的年龄、性别、患肢左右差异没有统计学意义。A组51例，其中金标准下（诊断前交叉韧带损伤的金标准：关节镜检）确诊前交叉韧带损伤的研究对象49例，前交叉韧带未损伤的研究对象2例。所以本研究中当Blumensaat角≤ 0°时，指示损伤的符合率达96.07%。B组116例，ROC曲线下面积为0.910，对应的最佳诊断界点值为15°，敏感性达70.0%，特异性达95.8%。即Blumensaat角≥ 15°时指示前交叉韧带损伤的概率较大，当0°< Blumensaat角< 15°时多指示前交叉韧带未损伤。而后将Blumensaat角≤ 0°及≥ 15°作为诊断前交叉韧带损伤的指标，与关节镜镜检结果比较，测得总样本的符合率为92.8%。
结论：Blumensaat角对于前交叉韧带损伤的诊断有价值。利用Blumensaat角辅助诊断前交叉韧带损伤时，当角度≤ 0°或≥ 15°时，前交叉韧带损伤的概率较大。 |

| Diagnostic value of Blumensaat angle for anterior cruciate ligament injury |

ABSTRACT
Objective: The receiver operator characteristic(ROC) curve was used to determine the best Blumensaat angle for the diagnosis of anterior cruciate ligament injury,so as to objectively evaluate the diagnostic value of Blumensaat angle for anterior cruciate ligament injury.
Methods: Total 167 patients who had knee arthroscopic treatment in a hospital from January 2015 to January 2016 were retrospectively studied,and the patients' age,gender,left and right limb condition were recorded. The patients were divided into two groups according to Blumensaat angle measured on the MRI:group A(Blumensaat angle ≤ 0°),and group B(Blumensaat angle >0°). The ROC curve was drawn from the statistical data of the group B to get the best critical value of the anterior cruciate ligament injury when the Blumensaat angle was more than 0°. According to the best critical value obtained by ROC curve,the coincidence rate of the total sample was obtained.
Results: There were no significant differences in patients' age,gender,and affected limbs. There were 51 patients in group A,in which 49 patients were diagnosed as anterior cruciate injury under arthroscopy(gold standard for diagnosis of anterior cruciate ligament injury),and 2 patients were diagnosed as no anterior cruciate injury under arthroscopy. When the Blumensaat angle was<0°,the coincidence rate was 96.07%. In group B(116 cases),the area under the ROC curve was 0.910,the best cutoff corresponds to 15°; the sensitivity was 70.0%,and the specificity was 95.8%. When the Blumensaat angle was ≥ 15°,the probability of anterior cruciate ligament injury was greater. When the Blumensaat angle was 0° to 15°,the anterior cruciate ligament was more likely to be not injured. The Blumensaat angle ≤ 0°or ≥ 15° were used to diagnose the injury of anterior cruciate ligament. Compared with the results of arthroscopy,the coincidence rate of the total sample was 92.8%.
Conclusion: Blumensaat angle is helpful to diagnose the ACL injuries. When the Blumensaat angle was ≤ 0° or ≥ 15°,the probability of ACL injury is greater. |
