文题释义:
盘状半月板:盘状半月板也称盘状软骨,是一种先天性半月板解剖变异。因其自身形态失去正常半月形而呈近似圆盘形而得名。其中外侧盘状半月板的发生率明显高于内侧,而且其在东亚人群中的发病率较高。
症状性外侧盘状半月板:相较正常形态半月板而言,由于外侧盘状半月板自身形态学及组织学存在异常,因此更容易损伤。而外侧盘状半月板损伤后会引发膝关节疼痛、弾响、交锁以及屈伸活动受限等临床症状,因此称为症状性外侧盘状半月板。
摘要
背景:
目前,盘状半月板损伤后的形态学变化规律尚未完全明确,用于评价盘状半月板损伤的形态学指标还有待进一步探索研究。
目的:比较症状性与非症状性成人外侧盘状半月板在MRI冠状面上的形态学差异,进而筛选出评价外侧盘状半月板损伤的形态学指标。
方法:纳入36例(36膝)症状性成人外侧盘状半月板病例(研究组)和34例(34膝)非症状性成人外侧盘状半月板病例(对照组),采用GE Healthcare Centricity RIS/PACKS系统,在膝关节 MRI冠状面图像上测量并采集2组病例外侧盘状半月板的主要形态学指标,所得数据进行wilcoxon秩和检验。
结果与结论:①研究组外侧盘状半月板冠状面体部宽度显著大于对照组(P < 0.001);②研究组外侧盘状半月板冠状面游离缘高度显著大于对照组(P < 0.001);③研究组外侧盘状半月板关节囊缘高度显著小于对照组(P=0.002);④外侧盘状半月板体部高度以及股骨外侧髁宽度两组间比较差异无显著性意义(P > 0.05);⑤研究组外侧盘状半月板体部宽度与股骨外侧髁宽度比值、外侧盘状半月板游离缘高度与体部高度比值均大于对照组(P < 0.001),而关节囊缘高度与体部高度比值小于对照组(P < 0.001)。⑥结果说明,相较非症状性成人外侧盘状半月板而言,症状性成人外侧盘状半月板冠状面体部宽度以及游离缘高度增加,而关节囊缘高度降低,外侧盘状半月板体部宽度与股骨外侧髁宽度比值、外侧盘状半月板游离缘高度与其体部高度比值可以作为评价成人外侧盘状半月板损伤的有效影像学指标。

Abstract:

BACKGROUND: Currently, the morphologic changes of the discoid lateral meniscus (DLM) remain unclear, and morphological indexes used to evaluate the injuries of DLM still need to be explored.
OBJECTIVE: To compare the MR imaging difference between symptomatic and asymptomatic DLM in adults, and to select reliable morphological parameters for assessing DLM.
METHODS: A total of 36 patients (36 knees) with a symptomatic DLM (study group) and 34 patients (34 knees) with an asymptomatic DLM (control group) were included in this study. GE Healthcare Centricity RIS/PACKS System was used to measure the primary morphological parameters of two patients with DLM on coronal MR imaging. Intergroup comparison was performed with the Wilcoxon test.
RESULTS AND CONCLUSION: On the coronal MR imaging, the width of the body portion and height of the free edge of the DLM was significantly increased in the study group compared with the control group (P < 0.001), while the height of the peripheral portion which connects with the capsule of the DLM was significantly decreased in the study group compared with the control group (P = 0.002). The height of the middle of the DLM and the width of the lateral femoral condyle showed no significant differences between the both groups (P > 0.05). The width ratio of the body of the DLM to the lateral femoral condyle and the height ratio of height of the free edge to the middle of the DLM were significantly increased in the study group compared with the control group (P < 0.001), while the height ratio of the peripheral portion to the middle for the DLM was significantly decreased compared with the control group (P < 0.001). These findings suggest that compared with asymptomatic discoid lateral meniscus, the width of the body portion and the height of the free edge for the DLM are increased; however, the height of the peripheral portion which connects with the capsule of the DLM is decreased. The width ratio of the body portion of the DLM to the lateral femoral condyle and the height ratio of the free edge to the middle for the DLM may be reliable morphological parameters for the assessment of the DLM in adults.
