Questionnaire to Identify Knee Symptoms: Development of a Tool to Identify Early Experiences Consistent With Knee Osteoarthritis

BACKGROUND: Current diagnostic procedures for knee osteoarthritis (OA) identify individuals late in the disease process. A questionnaire may be a useful and inexpensive method to screen for early symptoms of knee OA. OBJECTIVE: The purpose of this study was to develop a brief, self-administered questionnaire for clinical and research settings to identify emerging knee problems in people who could benefit from conservative interventions.
