Behavioral Incentives for Exercise and Intra‐Articular Corticosteroids for Knee Osteoarthritis: Results from a Factorially Designed Pragmatic Randomized Clinical Trial

Key Points

• To assess the effectiveness of behavioral incentives for exercise and intra-articular corticosteroid injections on knee osteoarthritis (KOA) symptoms.
• Conducted a factorially designed pragmatic randomized clinical trial.
• Involved patients with symptomatic knee osteoarthritis.
• Compared behavioral incentives to promote exercise and corticosteroid injections against lidocaine-only injections.
• Behavioral incentives increased physical activity but did not improve KOA symptoms.
• Corticosteroid injections showed no added benefit over lidocaine injections.
