文题释义:
双前交叉韧带征:双前交叉韧带征是外侧半月板发生桶柄撕裂的一种MRI成像表现。即失稳的外侧半月板桶柄移位至前交叉韧带外后方并与之共同成像在MRI矢状面上,因呈现类似2条前交叉韧的影像学征象而得名。
盘状半月板:盘状半月板是一种先天性半月板形态异常,以外侧者居多,因其形态近似圆盘而得名。相较正常外侧半月板,外侧盘状半月板更容易撕裂,且半月板失稳和移位的现象较为普遍。外侧盘状半月板损伤的膝关节发生疼痛、弾响和屈伸活动受限的风险更高,膝关节功能受损也更严重,因此是关节镜手术治疗的指征。
 
摘要
背景:双前交叉韧带征是外侧半月板桶柄撕裂的影像学表现,然而其与外侧盘状半月板撕裂类型的关系仍不明确。
目的:探讨双前交叉韧带征对成人外侧盘状半月板损伤失稳的评价作用和价值。
方法:回顾95例成人外侧盘状半月板损伤病例的临床及影像资料,由2名影像学主任医师观察并分析入组病例的膝关节MRI图像。统计术前MRI检查中双前交叉韧带征的发生率,分析其与外侧盘状半月板撕裂类型、手术方式以及患者临床症状的关系。
结果与结论:①95例外侧盘状半月板损伤病例中双前交叉韧带征阳性17例,阳性率为18%;②完全型外侧盘状半月板中双前交叉韧带征的发生率为29%,明显高于不完全型的7%(P=0.005);双前交叉韧带征阳性组中纵向撕裂和边缘撕裂的发生率分别为35%和41%,也明显高于阴性组的9%(P=0.013)和14%(P=0.025);③双前交叉韧带征阳性组中术前膝关节弹响(P=0.021)、伸膝活动受限的发生率(P=0.003)、术中半月板缝合的概率(P=0.010)以及术前疼痛目测类比评分等(P=0.008)均显著高于阴性组,而术前Lysholm膝关节功能评分明显低于阴性组(P=0.020);④提示双前交叉韧带征是成人外侧盘状半月板损伤失稳的影像学征象,其在外侧盘状半月板损伤评价和治疗中具有一定价值。

Abstract:

BACKGROUND: Double anterior cruciate ligament sign is a imaging performance of the bucket handle tear of lateral meniscus. While, the relationship between double anterior cruciate ligament sign and the tearing type of discoid lateral meniscus is still unclear.

OBJECTIVE: To investigate the meaning and value of double anterior cruciate ligament sign on the instability of torn discoid lateral meniscus in adults.
METHODS: Clinical and imaging data of 95 cases of torn discoid lateral meniscus were retrospectively reviewed. All MRI images of the knee were observed and analyzed by two chief physicians of radiology. The incidence of double anterior cruciate ligament sign on preoperative MRI was calculated, and the relation between double anterior cruciate ligament sign and tearing type, surgical method and clinical symptoms of torn discoid lateral meniscus were analyzed.
RESULTS AND CONCLUSION: (1) Among 95 knees with torn discoid lateral meniscus, 17 knees (18%) were diagnosed as definite double anterior cruciate ligament sign. (2) The incidence of double anterior cruciate ligament sign in complete discoid lateral meniscus was 29%, which was significantly higher than that of 7% in incomplete discoid lateral meniscus (P=0.005). The incidences of longitudinal tear and peripheral tear were 35% and 41% in positive group of double anterior cruciate ligament sign, which were significantly higher than that of 9% (P=0.013) and 14% (P=0.025) in negative group. (3) The cases of preoperative click (P=0.021), extension block (P=0.003), the Visual Analogue Scale score (P=0.008) of the knee and the intraoperative meniscus suture (P=0.010) in positive group of double anterior cruciate ligament sign were significantly higher than those in the negative group, while the Lysholm score was lower than that in the negative group (P=0.020).(4) Our findings indicate that double anterior cruciate ligament sign is a MR imaging feature associated with a displaced tear of the discoid lateral meniscus in adults. Therefore, it may be a reliable indicator for evaluating the tear pattern and the operation method for adult patients with torn discoid lateral meniscus.
