Hip joint replacement—also known as total hip arthroplasty—is a widely performed orthopedic surgery designed to replace a deteriorated or injured hip joint with a prosthetic implant. The procedure is typically recommended when conservative treatments, such as medication, physical therapy, and lifestyle modifications, no longer provide sufficient relief from pain or restore functional movement.

During the surgery, the damaged portions of the hip joint, including the femoral head and the acetabular socket, are removed and replaced with artificial components made of metal, ceramic, or durable plastic. These implants are engineered to mimic the natural movement of the joint, offering improved stability and long-term relief.

Hip joint replacement can benefit individuals suffering from osteoarthritis, rheumatoid arthritis, fractures, avascular necrosis, or other degenerative conditions. Most patients experience a significant reduction in pain, increased mobility, and a better overall quality of life after recovery. With advances in surgical techniques and materials, modern hip replacements are highly effective and can last for many years, enabling patients to return to daily activities with confidence.
