目的：本研究的目的是探讨内侧半月板（MM）纵向撕裂及其半月板修复对前交叉韧带（ACL）损伤患者内侧半月板挤压的影响。本研究的假设基础是MM的纵向撕裂与MM挤压相关，并且在ACL重建并伴随MM修复后挤压将持续存在。方法：将43例伴有MM纵裂的acl损伤患者纳入MM纵裂组。34例无半月板损伤的单纯acl损伤患者作为对照组。术前及术后3个月mri测量内侧半月板挤压宽度（MEW）。结果：MM撕裂组术前MEW显著大于对照组（MM撕裂组：1.5 MM，对照组：0.3 MM, P < 0.001）。术后3个月，MM撕裂组MEW变化显著大于对照组（MM撕裂组0.8 MM，对照组-0.2 MM, P < 0.001）。MM撕裂组术前、术后缝线数与MEW相关（术前：P = 0.005, R = 0.42，术后：P < 0.001, R = 0.54）。结论：MM纵裂与MM挤压相关，且MM撕裂组ACL重建伴MM修复后MM挤压持续存在。初始半月板撕裂大小与术前MEW直接相关。因此，内侧半月板纵向撕裂后的半月板挤压应仔细考虑。(C) 2019 Elsevier B.V.版权所有
Purpose: The purpose of this study was to investigate the effect of a longitudinal tear of the medial meniscus (MM) and its meniscal repair on MM extrusion in anterior cruciate ligament (ACL)-injured patients. The hypothesis underlying this study was that a longitudinal tear of the MM is correlated with MM extrusion, and that the extrusion would persist after ACL reconstruction with concomitant MM repair.Methods: Forty-three ACL-injured patients with a concomitant MM longitudinal tear were included in the MM tear group. Thirty-four solely ACL-injured patients without any meniscal injuries were included in the Control group. Medial meniscus extrusion width (MEW) was measured pre-operatively and three months after surgery on magnetic resonance imaging.Results: Pre-operative MEW in the MM tear group was significantly larger than that in the Control group (MM tear group: 1.5 mm, Control: 0.3 mm, P < 0.001). The MEW change in the MM tear group was significantly greater than that in the Control group three months after operation (MM tear group: 0.8 mm, Control: -0.2 mm, P < 0.001). The number of sutures required for repair was correlated with MEW both pre-operatively and postoperatively in the MM tear group (pre-operative: P = 0.005, R = 0.42, postoperative: P < 0.001, R = 0.54).Conclusion: Longitudinal tear of the MM was correlated with MM extrusion and the MM extrusion persisted after ACL reconstruction with concomitant MM repair in the MM tear group. The initial meniscal tear size was directly correlated with the pre-operative MEW. Therefore, meniscal extrusion after longitudinal tears of the medial meniscus should be taken into careful consideration. (C) 2019 Elsevier B.V. All rights reserved.
