Patient-reported outcomes of meniscal repair and meniscectomy in patients 40 years of age and older show similar good results.

Abstract

The purpose of this study is to evaluate patient-reported outcome measures (PROMs) in patients aged 40years and older who underwent meniscal repair or meniscectomy. All patients aged 40 and older who underwent a meniscal repair at a single institution from 2006 to 2017 were included. Meniscal repair cases were matched with a meniscectomy control group in a 1:3 ratio, selected for an equal proportion of concomitant ACL reconstruction in each group. PROMs, collected at a minimum follow-up of 24months, included International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC), Marx activity scale, and a patient satisfaction scale. The primary outcome was IKDC score, which was compared between groups using a Mann-Whitney U test. Rate of failure, defined as repeat ipsilateral knee surgery or surgeon report of failure, was reported. Thirty-five meniscal repair patients and 131 meniscectomy patients were identified; 28 (80.0%) and 67 (51.1%) completed all PROMs with mean follow-up of 4.9 and 5.2years, respectively. The mean age was 48.5 ± 7.0years in the meniscal repair cohort and 52.8 ± 7.1years in the meniscectomy cohort (p = 0.009). Concomitant ACL reconstruction was present in 46.4% and 49.3% of the meniscal repair and meniscectomy cohorts, respectively (n.s.). The median IKDC score was 78 (IQR 66, 87) in the repair cohort and 77 (IQR 56, 86) in the meniscectomy cohort (n.s.). The median Marx activity scale was 3.5 (IQR 0, 8) in the repair cohort and 3.0 (IQR 0, 9) in the meniscectomy cohort (n.s.). Over 85% of both groups were satisfied or very satisfied with no between-group differences (n.s.). In patients aged 40years and older, patient-reported outcomes at an average of 5years postoperatively were satisfactory and similar in patients undergoing meniscal repair and meniscectomy, indicating that age alone should not be a contraindication to meniscal repair.Level of evidence: Level III.
