【摘要】：目的探讨膝关节内侧半月板半脱位对诊断后根部撕裂的价值。方法回顾性分析经关节镜证实的120例内侧半月板撕裂患者的MRI图像,将其中60例后根部撕裂患者作为后根部撕裂组,其他撕裂的60例作为对照组,于MRI图像上测量半月板突出长度,将半月板突出长度≥3mm定义为半月板半脱位,比较两组半月板半脱位的发生率。结果后根部撕裂组中,合并半月板半脱位者56例(56/60,93.33%),对照组中合并半月板半脱位者13例(13/60,21.67%),差异有统计学意义(χ2=60.15,P0.01)。内侧半月板半脱位提示后根部撕裂的敏感度、特异度及阳性似然比分别为81.16%(56/69)、92.16%(47/51)及10.35。结论膝关节内侧半月板半脱位可用以提示后根部撕裂。
[Abstract]:Objective to evaluate the value of medial meniscus subluxation in the diagnosis of posterior root tear. Methods the MRI images of 120 patients with medial meniscus tear confirmed by arthroscopy were retrospectively analyzed. 60 patients with posterior root tear were used as posterior root tear group and 60 patients with other tears as control group. The protruding length of meniscus was measured on MRI images. The meniscus protruding length 鈮，
