Osteoarthritis
Osteoarthritis (OA) is the most common form of arthritis, affecting millions of people worldwide, usually people over 55. It is a chronic (long-term) disease that occurs when the protective cartilage that cushions the ends of your bones wears down over time. Although OA can damage any joint, the disorder most commonly affects joints in your hands, knees, hips, and spine. OA is a degenerative joint disease that can cause pain, stiffness, and reduced function in the affected joints.
