Surgical Outcomes of Revision Meniscal Repair: A Case Series

[摘要] Background:Revision meniscal repair may yield better postoperative outcomes than meniscectomy. Few studies concerning the postoperative results of revision meniscal repair are available.Purpose:To evaluate the clinical outcomes following revision meniscal repair for meniscal retears after isolated meniscal repair.Study Design:Case series; Level of evidence, 4.Methods:The cases of 11 knees with ≥1 year of postoperative follow-up were retrospectively analyzed after they had undergone revision as a result of retear at the initial suture site between 2018 and 2024. We compared the patients' presurgical and final follow-up values on the Tegner sports activity score (Tegner score), Lysholm score, and International Knee Documentation Committee (IKDC) Subjective Knee Form by Wilcoxon signed-rank test. At 1 year postoperatively, the revision site was structurally evaluated by magnetic resonance imaging (MRI). To account for multiple comparisons across outcome measures, a Bonferroni correction was applied, with statistical significance set at a P value of < .02.Results:Of the 11 knees, 7 were male and 4 were female (median age at revision: 23 years; IQR, 17-32 years). The median Lysholm and IKDC scores both improved significantly from 57.0 (IQR, 40.0-81.0) and 50.8 (IQR, 37.9-72.4) before revision surgery to 91.0 (IQR, 90.0-100.0) and 88.5 (74.7-94.3) at the final follow-up (P = .002, r = 0.89; P = .002, r = 0.89), respectively. Postoperative MRI findings revealed low-signal intensity changes at the revision site in 8 of 11 patients, whereas 3 patients demonstrated persistent high-signal intensity.Conclusion:Our study showed that revision meniscal repair may improve short-term clinical results in carefully selected patients with retears. Further research is required to define optimal indications and techniques.
