Hip replacement, or hip arthroplasty, is a surgical procedure designed to relieve pain and restore function in a hip joint that has been damaged by arthritis, injury, or other conditions. This procedure is commonly recommended for individuals who suffer from chronic hip pain, stiffness, or limited mobility that has not responded to non-surgical treatments. During hip replacement surgery, the damaged parts of the hip joint are removed and replaced with artificial components, known as implants. These implants are typically made of metal, ceramic, or durable plastic, and are designed to replicate the natural movement and function of the hip joint. The procedure can involve a total hip replacement, where both the ball and socket of the joint are replaced, or a partial replacement, depending on the extent of the damage. Hip replacement surgery is known for its high success rate, offering significant pain relief and improved mobility for patients.
