Objective To identify trajectories of patient-reported knee function over 5 years in patients with degenerative meniscal tears, and to explore whether baseline characteristics were associated sport recreational function. Design Prospective cohort study. Methods We conducted a secondary exploratory analysis the Odense-Oslo Meniscectomy Versus Exercise randomized controlled trial. Patient-reported was assessed Knee injury Osteoarthritis Outcome Score (KOOS) at baseline, 3 months, 1 year, 2 years, years. used group-based trajectory modeling subgroups who followed distinctive patterns change. Multinomial logistic regression examine associations patient demographics, function, disease-related factors KOOS subscale trajectories. Results The data from sample 140 participants identified for all subscales: (1) low, minimal improvement (10%-12% participants), (2) moderate, gradual (20%-36%), (3) high, early (53%-70%). Baseline prognostic deteriorating activities higher body mass index, poorer mental health, greater pain, lower perceived quadriceps hamstrings muscle strength, functional performance, more extrusion, radiographic signs osteoarthritis. Conclusion found distinct years: improvement, improvement. Nine every 10 improved least gradually after diagnosis tear. J Orthop Sports Phys Ther 2021;51(6):289–297.
