Changes and associations between gait biomechanics and knee inflammation after aspiration and corticosteroid injection for knee osteoarthritis.
Abstract
Although knee inflammation is thought to adversely affect joint function in patients with knee osteoarthritis (OA), the effects of reducing knee inflammation on gait biomechanics and strength are unknown. Our objectives were to compare ultrasound (US) measures of knee inflammation, gait biomechanics, knee extension and flexion strength, and pain before and after knee aspiration and corticosteroid injection; and explore associations among changes.
