Self-efficacy is considered a core component in self-management. Self-efficacy is a personal judgement of how well one can execute courses of action required to deal with chronic processes. However, there is a lack of knowledge about the association between self-efficacy and health-related outcomes in osteoarthritis.
Epidemiological research estimates that the lifetime risk of developing symptomatic knee osteoarthritis (OA) is 45%<sup>1</sup>. Because of the shifting demographics with an increasing percentage of the US population older than 65 years, the burden of KOA will continue to increase<sup>2</sup>, <sup>3</sup>. Although a recent randomized controlled trial demonstrated that total knee replacement is more effective than nonsurgical treatment of end-stage knee OA<sup>4</sup>, effective nonsurgical treatments are required to manage knee OA until surgical intervention becomes medically necessary.
