Primary outcomePrimary: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Scale — 3.3; 3.0; 2.9 units on scale
Summary
Patients undergoing knee replacement surgery and who have high levels of pain catastrophizing are at risk for poor outcome. The clinical trial is designed to determine if a pain coping skills training intervention delivered by physical therapists and supervised by psychologists is more effective at reducing pain and improving function and is more cost effective than arthritis education or usual care.
