Joint replacement is a surgical procedure where a damaged joint is removed and replaced with an artificial joint, often made of metal, plastic, or ceramic. This procedure is commonly performed on joints like the knee, hip, and shoulder to relieve pain and restore function, especially in patients with conditions like Osteoarthritis or Rheumatoid Arthritis. The surgery can significantly improve the quality of life for individuals suffering from chronic joint pain. Recovery typically involves physical therapy to regain strength and mobility, allowing patients to return to their daily activities with greater ease and comfort.
