Hip replacement surgery is a medical procedure that involves removing a damaged or worn-out hip joint and replacing it with an artificial joint, known as a prosthesis. This surgery is often recommended for individuals suffering from severe hip pain or limited mobility due to conditions like osteoarthritis or rheumatoid arthritis. The goal is to relieve pain and improve function, allowing patients to return to their daily activities. The procedure typically takes a few hours and is performed under general or regional anesthesia. After the surgery, patients usually spend a few days in the hospital for recovery and rehabilitation. Physical therapy is an essential part of the recovery process, helping patients regain strength and mobility in their new hip joint.
