Total Hip Replacement (THR) or Total Hip Arthroplasty (THA) is a surgical procedure that replaces worn or damaged parts of your hip joint. The diseased joint’s surfaces are removed and replaced with a mechanical, artificial joint known as a prosthesis. This surgery can help you get rid of the pain and stiffness in your hip joint.
The femur and pelvic parts of your new hip prosthesis are made of metals and plastics. The cup replaces your pelvic hip socket’s worn hip socket. The ball is used to replace the worn end of your thigh bone (femur). The ball is connected to a stem that is inserted into your femur. The cup and stem are sometimes cemented in place with special bone cement, or the metals may have a porous surface into which bone grows to create a tight fit. The prosthesis has a lifespan of 10 to 15 years. However, it may become worn and loose over time, necessitating a hip replacement.
