Osteoarthritis vs. rheumatoid arthritis
HEALTH GUIDE REFERENCE FROM A.D.A.M

Osteoarthritis is a deterioration of cartilage and overgrowth of bone often due to "wear and tear." Rheumatoid arthritis is the inflammation of a joint's connective tissues, such as the synovial membranes, which leads to the destruction of the joint's cartilage.
