| 摘 要： | 目的 探讨膝板股韧带附着区外侧半月板后角（PHLM）撕裂的MRI表现及鉴别诊断价值。 方法 选取2012年12月至2018年6月因前交叉韧带（ACL）损伤在南通市通州区中医院就诊的35例膝板股韧带附着区PHLM撕裂患者作为观察组，搜集同期30例ACL损伤但非PHLM撕裂患者作为对照A组，另选取同期例行体检的30名健康者作为对照B组。3组受试者均行膝关节MRI检查，观察3组受试者的MRI表现。分别应用χ 2检验、单因素方差分析和t检验分析膝关节MRI征象的发生率、膝关节周围结构的损伤情况及膝关节线状高信号影显示的层数和长度，并采用受试者工作特征（ROC）曲线分析鉴别诊断PHLM真、假性撕裂的效能。 结果 观察组患者在MRI矢状面和横断面图像上均表现为明显的PHLM周缘部线状高信号，矢状面上可连续检出（5.75±1.38）层（称“连续线征”），横断面上自内向外延伸（15.06±5.02）mm（称“拉链征”），与对照A组、B组比较差异均有统计学意义（F=43.231、36.113，均P<0.05）。以“连续线征”和“拉链征”作为阳性标准，MRI诊断膝板股韧带附着区PHLM撕裂的灵敏度为85.71%、特异度为95.00%、准确率为91.58%。 结论 膝板股韧带附着区PHLM撕裂在MRI上有明显的征象，辅以“连续线征”和“拉链征”进行鉴别诊断，可明显提升诊断效果。

| Abstract: | Objective This study aims to investigate the MRI appearance and diagnostic value of the posterior horn of the lateral meniscus (PHLM) tear of the knee ligament attachment zone. Methods From December 2012 to June 2018, 35 patients with anterior cruciate ligament (ACL) injury combined with PHLM tear in the knee ligament attachment zone were selected as the observation group. Thirty patients with ACL injury but without PHLM tears were collected as the control group A. Another 30 healthy people who received routine physical examination were selected as the control group B. All subjects received knee MRI examination. The MRI performance of all subjects in the three groups was observed. χ2 test, one-way ANOVA, and t-test were used to calculate the incidence of knee MRI signs, the damage of the structure around the knee joint, and the number and length of the linear high-signal images of the knee joint. The receiver operating characteristic curve was used to analyze the effectiveness of differential diagnosis of true and false tear in PHLM. Results Patients in the observation group showed significant linear hyperintense on the MRI sagittal plane and cross-sectional images. The sagittal plane was continuously detected (5.75±1.38) layers (called "continuous line sign"), extending from the inside to the outside (15.06 ± 5.02) mm (called "zipper sign"). The number of layers on the sagittal plane and the length of the transverse section in the observation group were higher than those in the control groups A and B ( F =43.231, 36.113, both P < 0.05). Combined with "continuous line sign" and "zipper sign" as the positive criteria, the sensitivity was 85.71%, the specificity was 95%, and the accuracy was 91.58%. Conclusion The PHLM tear in the knee ligament attachment zone had obvious signs on MRI, supplemented by "continuous line sign" and "zipper sign" for differential diagnosis, which could significantly improve the diagnostic effect. |
