INTRODUCTION: Newly symptomatic osteoarthritis (OA) is often misinterpreted as new pathology or injury, which is associated with pain intensity and incapability. METHODS: Adult patients with hip and knee OA completed measures of catastrophic thinking, depression, capability, symptom duration, and perceived injury. RESULTS: Symptom duration was associated with OA grade and symptoms of depression. Perceived injury was common (31%) and associated with men and knee arthritis. Capability was associated with misinterpretation of symptoms and the work status 'other,' but not radiographic severity. CONCLUSIONS: Misinterpretation of OA symptoms is common and has a greater influence on capability than radiographic grade of pathophysiology.
