Pain Coping Skills Training
The pain coping skills training will be delivered by physical therapists in eight one-hour sessions by telephone over a 2-month perioperative period. Patients will be taught a variety of skills designed to improve maladaptive pain related thoughts and actions to enhance recovery following arthroplasty. Pain Coping Skills Training
Arthritis Education
The eight one-hour perioperative arthritis education sessions will be delivered by nurse educators via telephone and will use a presentation and discussion format. Figures and discussion sessions will present information on the nature of arthritis, what to expect following knee arthroplasty, treatment of osteoarthritis, the role of exercise, joint protection and making future treatment decisions.
