MRI与关节镜诊断膝关节韧带损伤的比较研究

MRI and arthroscopic correlation in knee ligament injuries

目的：探讨MRI对膝关节韧带损伤的诊断准确率及其对临床治疗的指导意义。方法：90例关节镜及手术患者术前行MRI检查,根据MRI诊断分为1~3级损伤,将MRI诊断结果与关节镜下及手术所见进行对比。结果：根据MRI表现,经关节镜及手术对照诊断准确率分别为CL 93.8%（76/81）、PCL 100%（32/32）、MCL 93.8（61/65）、LCL89.5（17/19）,总诊断准确率为94.4%。结论：MRI是诊断膝关节韧带损伤的重要无创性检查方法,提高MRI诊断准确率对筛查韧带损伤及手术治疗有指导性意义。

Objective：To investigate the diagnostic accuracy of MRI on the knee ligament injury and discuss its impact on clinical practice.Methods：90 cases with MRI examination before arthroscopy and surgery,according to MRI diagnosis of injury is divided into 1～3 grade,the results of MRI and arthroscopic diagnosis and surgical findings were compared.Results：The MRI diagnostic accuracy was ACL 93.8%（76/81）,PCL 100%（32/32）,MCL 93.8（61/65）,LCL 89.5（17/19）, with a total diagnostic accuracy was 94.4%,according to arthroscopy and surgery.Conclusion：MRI is a well,non-invasive method of assessing knee ligament injury. To improve diagnostic accuracy of MRI is guiding significance for screening and surgical treatment of ligament injury.
