Long-term effectiveness of exercise therapy in patients with osteoarthritis of the hip or knee: A randomized controlled trial comparing two different physical therapy interventions

149 patients with osteoarthritis of knee or hip, diagnosed by the clinical criteria of American College of Rheumatology, were randomized to structured exercise therapy (behavioral graded activity) or usual exercise. At 60 month follow up, no significant long-term differences between the two forms of exercise were noticeable. However patients with Hip OA, were found to have lesser rates to opt for Total Hip Athroplasty with the BGA therapy that could perhaps be explained by the better short and midterm outcomes with BGA.
