"胫骨平台比"和前内侧半月板突出度在后交叉韧带损伤诊断中的应用对比观察
A comparative analysis of application of the"tibial plateau ratio"and the protrusion of the anterior medial meniscus in diagnosis of posterior cruciate ligament injuries
摘要
Abstract
Objective To compare the diagnostic efficacy of the"tibial plateau ratio"and the protrusion of the ante-rior medial meniscus(PAMM)in diagnosing posterior cruciate ligament(PCL)injuries.Methods Sixty-nine patients with arthroscopically confirmed PCL injuries were classified as the PCL injury group,while 72 patients with other knee joint disorders,without PCL injuries,were designated as the PCL normal group.Patients in both groups underwent knee MRI examination,during which the PAMM and the tibial plateau ratio were quantified using the RadiAnt DICOM Viewer.Receiver operating characteristic(ROC)analysis was conducted to assess the diagnostic efficacy of the tibial plateau ratio and PAMM,and the cut-off value was determined by calculating the maximum Youden index method.Results In the PCL injury group,the tibial plateau ratio and PAMM were 0.38(0.31,0.41)and 3.30(2.67,3.94)mm,respective-ly;in contrast,the corresponding measurements in the PCL normal group were 0.50(0.44,0.54)and 2.17(1.83,2.48)mm,with statistically significant differences between these two groups(all P<0.05).The area under the curve(AUC)of the tibial plateau ratio in diagnosing PCL injuries was 0.87,reflecting a sensitivity of 0.86 and a specificity of 0.82 at a cut-off value of 0.43.In comparison,the AUC of PAMM in diagnosing PCL injuries was 0.88,demonstrating a sensitivity of 0.71 and a specificity of 0.92 at a cut-off value of 2.86 mm.Conclusion The diagnostic efficacy of the tib-ial plateau ratio and PAMM in PCL injuries is equivalent.关键词
