KNEE OSTEO ARTHRITIS - AN OVERVIEW

Abstract

Abstract
Osteoarthritis (OA) or degenerative joint disease, is one of the oldest and most common type of arthritis. With research continuing on all arthritic disorders, OA is no longer believed to be a wear and tear disease that is a normal consequence of aging. Although aging does lead to decreasing quality and quantity of the proteoglycans in articular cartilage, the changes seen in the cartilage of asymptomatic adults are quite different from those found in people with OA. OA is now recognized as a chronic, progressive, process in which new tissue is produced in response to joint insults and cartilage deterioration.
