This study was initiated to evaluate the long-term outcome of meniscal sutures and to correlate clinical findings with MRI findings. We were interested to see if a clinically healed meniscus also showed as such on MRI and if degenerative changes were present
We studied prospectively 13 patients (7 men) aged between 29 and 50 years, who had undergone closed meniscus repair between 1985 and 1988 using an inside-out technique, clinically and with MRI, with a mean follow-up time of 13 years.
Meniscal suture gave good clinical long-term results: all patients got a Hospital for Special Surgery score of more than 75%. In all patients the site of the previous suture was still visible on MRI, mainly from small metal artefacts in the meniscus. 4 of 7 patients with an unrepaired ACL lesion had signs of arthrosis and cartilage degeneration. MRI showed signs of mucoid degeneration or scar tissue in 6/13 of the patients.
We believe that asymptomatic meniscal tears produce abnormal MR signals even though they have stable unions, and that MR signals at the site of repair represent edematous scar tissue, not true nonunions.
本研究旨在评估半月板缝合的长期效果，并将临床结果与MRI结果相关联。我们想了解临床上愈合的半月板在MRI上是否也显示如此，以及是否存在退行性改变。
我们前瞻性地研究了13例年龄在29至50岁之间的患者（7例男性），他们在1985年至1988年间采用由内向外技术进行了半月板闭合修复，并进行了临床和MRI检查，平均随访时间为13年。
半月板缝合取得了良好的长期临床效果：所有患者的特种外科医院评分均超过75%。在所有患者中，先前缝合的部位在MRI上仍可见，主要是由于半月板内的小金属伪影。7例未修复前交叉韧带损伤的患者中有4例出现关节病和软骨退变迹象。MRI显示6/13的患者有黏液样变性或瘢痕组织迹象。
我们认为无症状的半月板撕裂即使有稳定的愈合也会产生异常的MR信号，并且修复部位的MR信号代表水肿性瘢痕组织，而非真正的未愈合。
