Condition: Degenerative joint disease, also known as osteoarthritis (OA), is a common “wear-and–tear” disease.  The underlying cause of this condition is typically chronic repetitive motion that results in inflammation and structural joint damage.  Inflammation causes pain, redness, and swelling. The tiniest amount of trauma triggers inflammation as the body attempts to clean-up/protect damaged tissue.  This cycle of joint damage and inflammation leads to the break-down of cartilage that serves as a smooth gliding surface and cushion in the joints.  Any joint can be affected, but frequently found in the knees, hands, hips, and spine.   Background: More than 50% of adults over the age of 65 are affected by degenerative joint disease. This condition is associated with pain, loss of function, and reduced endurance, ultimately leading to weight gain and associated complications. Credit: aapmr.org
