Therefore, we aimed to compare meniscal surgery to early exercise therapy and patient education.Materials and Methods In a randomized controlled trial, 121 patients aged 18–40 years with a MRI-verified meniscal tear were randomized to surgery or 12-weeks supervised exercise and education. For this study 63 patients (33 and 30 patients in surgery and exercise groups, respectively) reporting baseline mechanical symptoms were included. Primary outcome was self-reported mechanical symptoms (yes/no) at 3, 6, and 12 months assessed using a single item from the Knee Injury and Osteoarthritis Outcome Score (KOOS). Secondary outcomes were KOOS4 and the 5 KOOS-subscales and the Western Ontario Meniscal Evaluation Tool (WOMET).Results In total, 55/63 patients completed the 12-month follow-up. At 12 months 9/26 (35%) in the surgery group and 20/29 (69%) in the exercise group reported mechanical symptoms. The risk difference and relative risk at any time point was 28.7% (95% CI 8.6 to 48.8) and 1.83 (95% CI, 0.98 to 2.70) of reporting mechanical symptoms in the exercise group compared with the surgery group. No between group differences were found in secondary outcomes.Conclusion Surgery seems to be more effective for relieving self-reported mechanical symptoms, but not for improving pain, function and quality of life in young patients with a meniscal tear and mechanical symptoms compared with a strategy of exercise and education.
