Implementation of Group Physical Therapy for Knee Osteoarthritis

Is an enhanced implementation support approach superior to less intensive foundational implementation support for promoting delivery of a group physical therapy program for knee osteoarthritis?In this cluster randomized clinical trial including 19 sites and 144 patients, sites receiving enhanced implementation support did not have significantly greater penetration (patients enrolled per month) or fidelity (number of classes per patient) compared with sites receiving foundational support. The rate of adoption was high for both arms, but penetration was relatively low.In this study, enhanced implementation support did not outperform foundational support, suggesting different implementation approaches are likely needed to adequately support penetration.
