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 procedure typically takes a few hours and can be performed using traditional or minimally invasive techniques. After surgery, patients usually undergo physical therapy to help regain strength and mobility in the hip. Most individuals can return to normal activities within a few months, significantly improving their quality of life.
