The Osteoarthritis Prevention Study
Osteoarthritis, Knee
The goal of this study is to establish the efficacy of an intervention of dietary weight loss, exercise, and weight-loss maintenance for knee Osteoarthritis (OA) prevention in adult females aged โฅ 50 years with obesity and no or infrequent knee pain. The primary aim is to compare the effects of a dietary weight loss, exercise, and weight-loss maintenance to an attention control group in preventing the development of structural Magnetic Resonance Imaging (MRI) knee OA. Secondary aims will determine the intervention effects on pain, mobility, health-related quality of life, knee joint compressive forces, inflammatory measures, weight loss, exercise self-efficacy, and cost-effectiveness of this intervention.
