Osteoarthritis meaning

Osteoarthritis is a degenerative joint disease that occurs when the protective cartilage that cushions the ends of bones wears down over time. It commonly affects the knees, hips, hands, and spine, leading to pain, stiffness, swelling, and reduced joint mobility. Osteoarthritis can result from aging, joint injury, or repetitive stress on the joints. Risk factors include obesity, genetics, and certain occupations. While there is no cure for osteoarthritis, treatment focuses on managing symptoms and improving joint function through a combination of medications, physical therapy, lifestyle changes, and, in severe cases, surgical interventions such as joint replacement.
