Osteoarthritis, also known as osteoarthrosis, degenerative arthritis or degenerative joint disease, is a degenerative disorder arising from the biochemical breakdown of articular cartilage in the synovial joints. It commonly affects the hands, hips and knees.

  • Pathophysiology Normal joints have little friction with movement and do not wear out with typical use, overuse, or most trauma. Hyaline cartilage is avascular, aneural, and alymphatic.[merckmanuals.com]
