Abstract

Forty-three knees in 43 patients were evaluated preoperatively with magnetic resonance imaging (MRI). Both menisci and cruciate ligaments subsequently were examined directly with arthroscopy. A grading scale was used to evaluate intrameniscal signal intensity and to predict the presence of meniscal tear using MR. Compared with arthroscopy, the sensitivity, specificity and accuracy of MRI were, respectively, 100%, 88% and 93% for tears of the medial meniscus; 72.7%, 93.7% and 88.4% for tears of the lateral meniscus; 100%, 96.7% and 97.7% for tears of the anterior cruciate ligament. There were no posterior cruciate ligament tears, and none were suggested from the images. Our results show that MRI is a valuable diagnostic aid in the management of traumatic knee injury.

摘要

对43例患者的43个膝关节进行了术前磁共振成像（MRI）评估。随后通过关节镜直接检查了半月板和交叉韧带。使用分级量表评估半月板内信号强度，并利用磁共振成像预测半月板撕裂的存在。与关节镜检查相比，MRI对内侧半月板撕裂的敏感性、特异性和准确性分别为100%、88%和93%；对外侧半月板撕裂的敏感性、特异性和准确性分别为72.7%、93.7%和88.4%；对前交叉韧带撕裂的敏感性、特异性和准确性分别为100%、96.7%和97.7%。没有后交叉韧带撕裂，图像中也未提示有后交叉韧带撕裂。我们的结果表明，MRI在创伤性膝关节损伤的管理中是一种有价值的诊断辅助手段。
