The purpose of this study was to assess the MRI features of the all-inside repaired meniscus in the long-term.
Among 27 consecutive all-inside arthroscopic meniscal repairs, 23 patients aged 25 ± 5 years at the time of surgery were reviewed at a median follow-up of 10 ± 1 years. Retrospective clinical examinations and imaging assessments using a 1.5-T MRI after all-inside arthroscopic meniscal repair were conducted.
At follow-up, Lysholm and IKDC averaged 89 ± 11 and 95 ± 8, respectively. MRI examinations revealed no meniscal signal alteration in three patients (13%), a vertical signal located in the previously torn area in seven (30%), a horizontal grade 3 in nine (39%), and a complex tear (grade 4) in four (17.5%). There were no differences between medial and lateral menisci (p = 0.15), stable and stabilised knees (p = 0.56).
Several abnormal vertical and/or horizontal hypersignals are still present on MRI examination ten years after arthroscopic all-inside meniscal repair. The appearance of early signs of osteoarthritis is rare, suggesting a chondroprotective effect of the repaired meniscus.
本研究旨在评估全内修复半月板的长期 MRI 特征。
在 27 例连续全内关节镜半月板修复中，对 23 例手术时年龄为 25 ± 5 岁的患者进行了回顾性研究，平均随访时间为 10 ± 1 年。对全内关节镜半月板修复后的患者进行回顾性临床检查和 1.5T MRI 影像学评估。
随访时，Lysholm 和 IKDC 平均评分为 89 ± 11 和 95 ± 8。MRI 检查显示 3 名患者（13%）无半月板信号改变，7 名患者（30%）在前次撕裂区域出现垂直信号，9 名患者（39%）出现 3 级水平信号，4 名患者（17.5%）出现复杂撕裂（4 级）。内侧和外侧半月板之间无差异（p = 0.15），稳定和稳定的膝关节之间也无差异（p = 0.56）。
全内关节镜半月板修复 10 年后，MRI 检查仍存在多个异常垂直和/或水平高信号。早期骨关节炎的出现很少见，这表明修复后的半月板具有软骨保护作用。
