Osteoarthritis is also referred to as degenerative joint disease and is the most common form of arthritis. The breaking down of cartilage in the joint causes pain, swelling and reduced motion. It is often accompanied by enlargement of the bones around the joint. Osteoarthritis can occur in any joint, but commonly affects the hands, knees, hips, and the spine. It is related to aging, genetics, and wear and tear on joints. The physicians of Arthritis & Rheumatology Associates of Palm Beach specialize in the treatment of osteoarthritis, including the use of medications, physical therapy, and appropriate localized injections which help relieve pain and stiffness.
