Background:
The management of meniscal radial tears has changed significantly in recent years in favor of meniscus repair. However, there is still limited published data on the outcomes and risk factors associated with repair failure. The objective of this study is to evaluate the clinical success rate of repaired meniscal radial tears and identify potential risk factors for failure.
Methods:
Patients who underwent repair of meniscal radial tears between 2016 and 2022 were reviewed retrospectively. The following parameters were collected: demographic data, pre-operative Kellgren-Lawrence grading, history of previous knee surgeries, time from injury to surgery, injury location, number of sutures used, use of transtibial tunnel augmentation, associated procedures, postoperative functional scores, and clinical failure rates.
Results:
81 patients were included, with a mean age of 29.9 ± 12.3 years. The mean follow-up time was 36.7 ± 17.0 months. Postoperatively, the mean IKDC was 81 ± 18.1, and the mean Lysholm score was 82 ± 18.4. The clinical failure rate was 19.8%. In the univariate analysis, the factors associated with failure included increased age, female gender, medial meniscus repair, isolated repairs (without ACL reconstruction), a Kellgren-Lawrence scale greater than 0, and repairs without a transtibial tunnel. However, none of these variables were statistically significant in the multivariate analysis adjusted for age and gender.
Conclusion:
The clinical success rate of repaired meniscal radial tears was about 80% after a minimum 2-year follow-up. Increased age, female gender, repair of medial meniscus, isolated repair without ACL reconstruction, mild preoperative osteoarthritic signs, and repair without a transtibial tunnel augmentation are possible risk factors for failure.
Level Of Evidence:
Level IV, retrospective case series.
