Routine screening for osteoarthritis is not indicated unless the patient is symptomatic.

Accurate data about the prevalence of OA can be useful for the health care system to have appropriate plans for management of OA patients. Nowadays, the OA screening in general population depends on the self-reported symptoms recorded during the clinical evaluation. An approved screening algorithm OA with sufficient sensitivities and specificities is necessary for OA management. Due to the lack of a reliable screening test for OA, the assessments of the prevalence of OA in a general population is difficult. Meanwhile, some scientist have worked on the screening questionnaires for identifying the knee or hip OA. Using only a questionnaire to identify OA cases without the physical examinations and radiographs would be non-verifiable^[1][2][2].
