Osteoarthritis, or degenerative joint disease, affects an estimated 20 million Americans, including many middle-age Americans ages 45-65. That’s why the American Academy of Orthopaedic Surgeons (AAOS) and the American Orthopaedic Society for Sports Medicine (AOSSM) are touting the benefits of a balanced fitness/exercise program in preventing, and easing the symptoms of, osteoarthritis.
With osteoarthritis, the articular cartilage that covers the ends of bones in the joints gradually wears away leaving a frayed, rough surface that causes painful joint motion. Osteoarthritis usually develops after many years of use, and most often affects people who are middle-aged or older. Other risk factors for osteoarthritis include obesity, previous injury to the affected joint, and/or family history of osteoarthritis.
