磁共振成像（MRI）已被广泛用于诊断尿道撕裂，但其诊断准确性，取决于类型和位置，还没有得到很好的研究。我们的目的是通过比较MRI和关节镜检查结果来评价MRI诊断的准确性。回顾了2005年至2018年的术前3.0 T MRI和关节镜检查结果，以确定半月板撕裂的存在、类型和位置。此外，根据前交叉韧带（ACL）损伤进行亚组分析。排除标准如下：（1）炎症性关节炎，（2）其他韧带损伤，（3）由于退行性关节炎导致的踝关节撕裂无法分类，（4）从MRI到手术超过90天，以及（5）数据不完整。在2998例合格患者中，最终纳入了544例。MRI诊断内侧半月板和外侧半月板撕裂的敏感性和特异性分别为91.8%和79.9%，80.8%和85.4%。ACL损伤组的MRI准确性低于ACL完好组（内侧半月板：81.7% vs. 88.1%，p = 0.041; 72.9% vs.外侧半月板：88.0%，p < 0.001）。ACL损伤组内侧半月板后角纵向撕裂的MRI准确性较低。MRI可以作为半月板撕裂的诊断工具，但在类型和位置分类方面的准确性有限。因此，由于术前MRI的诊断准确性较低，因此在ACL损伤患者的关节镜评估期间应小心。
Magnetic resonance imaging (MRI) has been widely used for the diagnosis of meniscal tears, but its diagnostic accuracy, depending on the type and location, has not been well investigated. We aimed to evaluate the diagnostic accuracy of MRI by comparing MRI and arthroscopic findings. Preoperative 3.0-T MRI and arthroscopic findings from 2005 to 2018 were reviewed to determine the presence, type, and location of meniscus tears. In addition, subgroup analysis was performed according to anterior cruciate ligament (ACL) injury. The exclusion criteria were as follows: (1) Inflammatory arthritis, (2) other ligament injuries, (3) inability to classify meniscal tears due to degenerative arthritis, (4) over 90 days from MRI to surgery, and (5) incomplete data. Of the 2998 eligible patients, 544 were finally included. The sensitivity and specificity of MRI in determining medial and lateral meniscus tears were 91.8% and 79.9%, and 80.8% and 85.4%, respectively. The accuracy of MRI in the ACL-injured group was lower than that in the ACL-intact group (medial meniscus: 81.7% vs. 88.1%, p = 0.041; 72.9% vs. lateral meniscus: 88.0%, p < 0.001). MRI accuracy was low for the longitudinal tears of the posterior horn of the medial meniscus in the ACL-injured group. MRI could be a diagnostic tool for meniscus tears, but has limited accuracy in their classification of the type and location. Hence, care should be taken during arthroscopic assessment of ACL-injured patients due to low diagnostic accuracy of preoperative MRI.
