Different Perspectives on Diagnosis and Prognosis of Hip and Knee Osteoarthritis in Primary Care

With the aging of the population, osteoarthritis is an increasing challenge for health care worldwide. Although osteoarthritis is the most frequently diagnosed joint disorder in primary care, no clear diagnostic set of criteria are available for primary care.
The overall aim of the work in this thesis was to identify early OA criteria for epidemiological research in primary care, and to establish the usefulness of radiographic signs widely used in epidemiological research and clinical practice.
