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

JBJoshua F. Baker KWKatherine D. Wysham MQMercedes Quiñones

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.

Abstract

Behaviorally-designed incentive programs can promote physical activity among patients with symptomatic KOA with no effect on KOA symptoms. Corticosteroid injections, compared to lidocaine-only injections, did not show a benefit.
