Osteoarthritis (OA) is the most common form of joint disease, and its impact is set to grow as the prevalence of obesity rises and our elderly population increases. Many clinicians regard OA as being simply a disease of 'wear and tear', and by implication one in which disease modification is not possible. Such prejudices have led to significant academic apathy in this disease that is reflected not only in our poor understanding of disease pathogenesis, but also in the failure to classify the disease with greater precision, and to develop sensitive tools for diagnosis and prognostic assessment. The recent identification of key degradative enzymes in cartilage and the use of mouse models to study disease pathogenesis have greatly changed our outlook. The next decade is likely to see significant advances in our understanding of, and treatment for, this condition. Crown Copyright © 2014 Published by Elsevier Ltd. All rights reserved.
