title: Osteoarthritis. Changing concepts in pathogenesis and treatment.
abstract: The clinical features of osteoarthritis provide little support for the traditional view of the disease as a wear-and-tear phenomenon of aging. In many cases osteoarthritis consists of a polyarthritis with mildly inflammatory features, such as stiffness, effusions, and hot Heberden's nodes. The finding of biochemical abnormalities of cartilage throws new light on this enormously important disease and suggests the possibility of more effective therapy.
