摘要
背景:前交叉韧带部分损伤后膝关节松弛程度的量化测量对于及时诊断、后期治疗和康复非常重要。现缺乏应用关节韧带测量仪进行前交叉韧带部分损伤诊断的相关研究。目的:探讨新型关节韧带数字体查仪在前交叉韧带部分损伤中的诊断价值。方法:纳入30名单侧前交叉韧带部分损伤患者及20名健康志愿者作为研究对象,应用国产新型关节韧带数字体查仪测量80,120,150 N三种负荷下每侧膝关节的胫骨向前位移值,比较前交叉韧带部分损伤组和对照组的胫骨向前位移值和双侧差异值,分析受试者工作特征曲线,计算曲线下面积,并确定新型关节韧带数字体查仪的诊断灵敏度及特异度。结果与结论:①前交叉韧带部分损伤组和对照组在年龄、性别、体质量指数和病程方面差异均无显著性意义(P>0.05);②前交叉韧带部分损伤组胫骨向前位移值的双侧差异值明显高于对照组(P<0.05),且前交叉韧带部分损伤组患侧的胫骨向前位移值明显高于健侧(P<0.05);③施加负荷在80 N时的诊断准确性最高(cutoff值=10.45 mm),曲线下面积为0.813(95%CI:0.708-0.919),敏感性和特异性分别为76.7%和70.0%;④提示新型关节韧带数字体查仪可以客观量化评估前交叉韧带部分损伤后的膝关节松弛度,可为怀疑前交叉韧带部分损伤的患者提供客观的诊断依据。
BACKGROUND:Quantitative measurement of knee laxity after partial anterior cruciate ligament injury is crucial for timely diagnosis,post-treatment,and rehabilitation.There is a lack of research on the use of articular ligament digital arthrometer in the diagnosis of partial anterior cruciate ligament injury.OBJECTIVE:To investigate the diagnostic value of a new articular ligament digital arthrometer in partial anterior cruciate ligament injury.METHODS:Totally 30 patients with partial anterior cruciate ligament injury and 20 healthy volunteers were included.The anterior tibial translation values under 80,120,and 150 N loads were measured by a homebred digital arthrometer.The anterior tibial translation and side-to-side difference were compared between the partial anterior cruciate ligament group and control group.The receiver operating characteristic curve was analyzed and area under curve was calculated,and the diagnostic sensitivity and specificity of the digital arthrometer were determined.RESULTS AND CONCLUSION:(1)There was no significant difference in age,sex,body mass index,and course of disease between the partial anterior cruciate ligament injury group and control group(P>0.05).(2)The side-to-side difference values of the partial anterior cruciate ligament injury group were significantly higher than those of the control group(P<0.05),and the anterior tibial translation values of the injured side were significantly higher than those of the healthy side in the partial anterior cruciate ligament injury group(P<0.05).(3)When the load was applied at 80 N,the diagnostic accuracy was highest(cutoff value=10.45 mm);the area under curve was 0.813(95%CI:0.708-0.919),and the sensitivity and specificity were 76.7%and 70.0%,respectively.(4)It is indicated that the digital arthrometer can objectively and quantitatively evaluate knee laxity after partial anterior cruciate ligament injury,and provide objective diagnostic basis for patients with partial anterior cruciate ligament injury.
