Rheumatoid arthritis is an inflammatory process that a person can get at any age. It is an auto immune disease. RA can be generalized. It is characterized by swelling, heat, redness and pain. Over time it can deform joints. Osteoarthritis is a wearing down of the bones where they meet at the joint. This usually happens as we age, or if we regularly do something that wears down a specific joint. There is no redness and heat in these joints, just the pain. It is usually not generalized, but occurs only in the joints that are being worn. Hips and knees are the most common.
