The Dangers of Osteoarthritis. Unlike rheumatoid arthritis, which is characterized by systemic inflammation, osteoarthritis is a localized disease that occurs only in the affected joints. With osteoarthritis, the thin layer of cartilage between the joints gradually erodes and wears away.
Osteoarthritis (also referred to as degenerative joint disease or wear-and-tear arthritis) is caused by the breakdown of joint cartilage. Cartilage acts as a cushion between the bones that form a joint. Cartilage loss can cause bone to rub on bone in a joint -- a condition that is very painful. Usually osteoarthritis begins in a single joint. Rheumatoid arthritis is a chronic, inflammatory type of arthritis. It is also classified as an autoimmune disease (i.e., immune cells attack the body's own healthy tissues). The synovium (lining of the joint) is primarily affected by rheumatoid arthritis, but organs body-wide can be affected as well.
