Total Hip Replacement (THR) or Total Hip Arthroplasty (THA) is a surgical procedure designed to replace the damaged or worn parts of the hip joint with a mechanical, artificial joint known as a prosthesis. This operation aims to alleviate pain and stiffness in the hip.

During the procedure, the surfaces of the affected joint are removed and replaced. The new hip prosthesis consists of metal and plastic components. The cup part of the prosthesis replaces the worn-out hip socket in the pelvis, while the ball component replaces the damaged end of the femur (thigh bone). The ball is attached to a stem that is inserted into the femur. The cup and stem may be fixed in place using special bone cement, or the metal parts may have a porous surface that allows bone to grow into it, securing a tight fit.

The lifespan of a hip prosthesis is typically between 10 and 15 years, though it may wear out and loosen over time, potentially requiring a revision surgery.
