Total Knee Replacement is a surgical procedure where damaged or worn-out parts of the knee joint are removed and replaced with artificial components. This surgery is often recommended for individuals suffering from severe knee pain due to conditions like osteoarthritis or rheumatoid arthritis. The goal is to relieve pain and restore function, allowing patients to return to daily activities. During the procedure, the surgeon makes an incision in the knee and removes the damaged cartilage and bone. The new artificial joint, typically made of metal and plastic, is then fitted into place. Recovery may involve physical therapy to help regain strength and mobility in the knee.
