Screening for Hip and Knee Osteoarthritis in the General Population: Predictive Value of a Questionnaire and Prevalence Estimates
Objective: To study the feasibility and validity of a two-step telephone screening procedure for symptomatic knee and hip osteoarthritis (OA) in the general population.
Method: The screening questionnaire was based on signs and symptoms, previous diagnosis of OA, and validated OA criteria. A random sample of telephone numbers was obtained and, at each number, one individual aged 40 to 75 years was included. A physical examination and knee or hip radiographs were offered when the screen was positive. A sample of individuals with negative screens was also examined. The diagnosis of hip/knee OA was based on either American College of Rheumatology criteria for signs and symptoms and Kellgren-Lawrence radiographic stage 2 or greater. Prevalence rates were estimated with correction for the performance of the screening procedure.
