Osteoarthritis is a common form of arthritis that occurs when the protective cartilage on the ends of your bones wears down over time. It typically affects joints like knees, hips, hands, and spine. Symptoms of osteoarthritis include pain, stiffness, swelling, and reduced range of motion in the affected joints. While there is no cure for osteoarthritis, treatment options aim to manage symptoms and improve joint function, such as nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, weight management, and assistive devices. In some cases, joint replacement surgery may be necessary. Regular exercise and a healthy lifestyle can also help manage the condition.
