Osteoarthritis is the most common chronic condition of the joints, affecting millions of people worldwide. OA can affect any joint but it occurs most often in knees, hips, lower back and neck, small joints of the fingers and the bases of the thumb and big toe. It occurs when the protective cartilage on the ends of your bones deteriorates over time. Cartilage is a protein substance that serves as a “cushion” between the bones of the joints. In OA, the cartilage breaks down, causing pain, swelling and problems moving the joint. In the body, an inflammatory process occurs and cytokines (proteins) and enzymes develop that further damage the cartilage. Eventually, if the cartilage wears down completely, you may be left with bone rubbing on bone leading to joint damage and more pain.
