Osteoarthritis is the most common type of arthritis. It happens when the smooth cartilage that cushions the ends of bones in a joint slowly wears down. Without enough cushioning, bones can rub together, which leads to pain and stiffness. Osteoarthritis often affects the knees, hips, hands, and spine. It usually develops slowly over many years and tends to become more common with age.
Common signs include joint pain, stiffness, swelling, and a reduced range of motion. Many people feel stiff in the morning or after resting, and pain often gets worse with activity. Some notice grinding or a “catching” feeling when they move the joint.
