Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage on the ends of your bones wears down over time.
Although osteoarthritis can damage any joint in your body, the disorder most commonly affects joints in your knees, hips, spine, shoulders, and hands.
Osteoarthritis symptoms can usually be effectively managed, although the underlying process cannot be reversed. Osteoarthritis symptoms often develop slowly and worsen over time. Signs and symptoms of osteoarthritis include: pain, tenderness, stiffness, loss of flexibility, grating sensation, and bone spurs.
