Hip replacement surgery, also known as total hip arthroplasty, is an advanced surgical procedure used to treat chronic hip joint conditions that cause pain, stiffness, and limited mobility. During the procedure, the damaged ball-and-socket joint is removed and replaced with prosthetic components made of metal, ceramic, or high-grade plastic. These implants are designed to replicate natural joint mechanics, ensuring smooth and stable movement. The surgery is performed under anesthesia and typically takes one to two hours. Modern techniques, including minimally invasive approaches, allow for reduced tissue damage, faster recovery, and long-term durability of the implant. It is widely regarded as one of the most successful orthopedic surgeries with high patient satisfaction and long-lasting results.
