Abstract
Objective
Meniscus root tear repair has been shown to lead to better long-term outcomes when compared to partial meniscectomy. It is unknown how age at the time of repair influences outcomes. This study's objective was to determine whether meniscus repair failure rates, subsequent contralateral knee surgery after a meniscus injury, and/or patient reported outcome (PRO) scores differ between older and younger age groups.
Methods
A retrospective review was performed of patients who underwent medial meniscus root repair by four surgeons at one tertiary academic institution between 2012-2019. Demographics and repair failure data were collected. Failure rate was defined as surgeon statement of failure and/or requiring surgery to the same meniscus. Patients were contacted to identify failures and obtain PRO measures. Failure rate, contralateral meniscus surgery rate, and PROs were compared between those older and younger than 60 years.
Results
105 patients were identified (62.9% female, 48.9∓12.5 years). At average follow-up 3.8∓2.5 years, there were 10 known repair failures (9.5%) and 20 known patients requiring surgery to the contralateral knee following a meniscus injury (19.0%). At average 5.9∓1.1 years post-surgery, with 28 responses, mean International Knee Documentation Committee (IKDC) score was 73.6∓20.2, mean Knee Injury and Osteoarthritis Outcome Score (KOOS) was 81.8∓16.7 median Tegner score was 4 (IQR:3-5), and median Marx activity score was 0 (IQR:0-4).
Risk of failure for patients greater than 60 years was 15.8% (3/19) and in patients younger than 60 years was 8.1% (7/86), p=0.38. The risk of requiring a contralateral knee surgery for patients greater than 60 years was 21.1% (4/19), and in those younger than 60 years was 18.6% (18/86), p=0.76. Average IKDC for those older than 60 was 75.1∓17.0 and 73.0∓21.8 for those younger (p=0.79). Average KOOS the older group was 84.6∓14.4 and 80.6∓17.8 for the younger (p=0.55). Median Tegner and Marx scores were 3.5 (IQR:3-5) and 0 (IQR:0-4), respectively, for the older group and 5 (IQR:3-6) and 0.5 (IQR:0-4) for the younger (p=0.57, p=0.87).
Conclusion
Meniscus repair failure rate and the rate of needing subsequent contralateral knee surgery was slightly greater for patients older than 60 years. However, these differences were not statistically significant. This may suggest that long-term outcomes following medial meniscus root repair are similar between older and younger patient groups, but further study is warranted with an increased sample size.
