This study aimed to evaluate whether functional outcome scores in patients over 60 years of age improve after arthroscopic medial meniscus posterior root repair using a soft suture anchor. Additionally, it aimed to compare postoperative outcomes between patients over 60 years and those under 60 years of age.
A retrospective cohort study of 30 patients who underwent medial meniscus posterior root repair between June 2019 and February 2023. The patients were divided into two groups (≥60 years, n = 15; <60 years, n = 15). Outcomes were assessed using the International Knee Documentation Committee (IKDC) and Lysholm scores at two years, along with MRI-based meniscus healing and radiographic osteoarthritis progression.
Both age groups demonstrated statistically significant improvement in functional scores at two years. In the ≥60 years age group, IKDC improved from 31.9 ± 8.8 to 61.5 ± 11.3 (P < 0.001) and Lysholm from 49.1 ± 14.9 to 87.6 ± 10.5 (P < 0.001). In the <60 years group, IKDC improved from 35.7 ± 10.4 to 54.3 ± 8.1 (P < 0.001) and Lysholm from 52.1 ± 19.3 to 82.0 ± 12.4 (P < 0.001). No statistically significant differences were observed between the groups for functional scores, meniscal healing (P = 0.352) or osteoarthritis progression (P = 0.762).
The patients aged ≥60 years who underwent arthroscopic medial meniscus posterior root repair using a soft suture anchor demonstrated functional improvements comparable to younger patients. Age alone should not be a contraindication for this procedure, though long-term follow-up is warranted to assess osteoarthritis progression.
Level III-retrospective cohort study.
本研究旨在评估使用软质缝线锚钉进行关节镜下内侧半月板后根修复后，60岁以上患者的功能结局评分是否有所改善。此外，还旨在比较60岁以上患者与60岁以下患者的术后结局。
对2019年6月至2023年2月期间接受内侧半月板后根修复的30例患者进行回顾性队列研究。患者分为两组（≥60岁，n = 15；<60岁，n = 15）。在两年时使用国际膝关节文献委员会（IKDC）和Lysholm评分评估结局，同时评估基于MRI的半月板愈合情况和影像学骨关节炎进展。
两个年龄组在两年时功能评分均有统计学意义的改善。在≥60岁年龄组中，IKDC评分从31.9±8.8提高到61.5±11.3（P < 0.001），Lysholm评分从49.1±14.9提高到87.6±10.5（P < 0.001）。在<60岁组中，IKDC评分从35.7±10.4提高到54.3±8.1（P < 0.001），Lysholm评分从52.1±19.3提高到82.0±12.4（P < 0.001）。两组在功能评分、半月板愈合情况（P = 0.352）或骨关节炎进展方面（P = 0.762）均未观察到统计学显著差异。
使用软质缝线锚钉进行关节镜下内侧半月板后根修复的60岁及以上患者，其功能改善情况与年轻患者相当。仅年龄不应成为该手术的禁忌证，不过需要进行长期随访以评估骨关节炎进展情况。
III级——回顾性队列研究。
