Knee osteoarthritis (OA) is a leading cause of pain worldwide. Although exercise can improve symptoms, joint replacement surgery is often used to treat OA. In this study, Belinda J Lawford and colleagues analyzed whether the use of X-ray imaging during diagnosis influences how OA is managed. In this randomized controlled trial, participants were asked to imagine that they went to a general practitioner with a painful knee. They then received an knee OA diagnosis either based on clinical symptoms or based on X-ray images. The use of X-rays during diagnosis increased the belief of participants that they needed joint replacement surgery. This study therefore suggests that the method of diagnosis could impact OA management practices.
