Revision hip replacement is a complex surgical procedure in which all or part of a previously implanted hip-joint is replaced with a new artificial hip-joint. Total hip replacement surgery is an option to relieve severe arthritis pain that limits your daily activities. During total hip replacement the damaged cartilage and bone is removed from the hip joint and replaced with artificial components. At times, hip replacement implants can wear out for various reasons and may need to be replaced with the help of a surgical procedure known as revision hip replacement surgery.
Revision hip replacement is advised in patients with the following conditions:
Revision hip replacement surgery is performed under general anesthesia. During the procedure, your surgeon will make an incision over the hip to expose the hip joint. Then the femur is dislocated from the acetabulum so that the old plastic liner and the metal socket can be removed from the acetabulum.
After removal, the acetabulum is prepared using extra bone and wire mesh to make up for the socket space and shape. Then the new metal shell is inserted into the socket using screws or special cement. A liner made of plastic, ceramic or metal is placed inside the metal socket.
To prepare the femoral component, the top of the femur bone is cut into several pieces to remove the implant. The segments of bone are cleaned and the new femoral implant is inserted into the femur either by a press fit or using bone cement. The segments of the femur and the femoral component are held together with surgical wires. Then the femoral head component made of metal or ceramic is placed on the femoral stem. All the new components are secured in place to form the new hip joint. The muscles and tendons around the new joint are repaired and the incision is closed.
After undergoing revision hip replacement, you must take special care to prevent the new joint from dislocating and to ensure proper healing. Some of the common precautions to be taken include:
As with any major surgical procedure, there are certain potential risks and complications involved with revision hip replacement surgery. The possible complications after revision hip replacement include:
Revision hip replacement removes your failed hip implants from a previous total hip replacement surgery, and replaces them with new ones, which will help make your hip strong, stable and flexible again. It improves mobility, strength and enables patients to return once again to normal activity with a pain-free hip.
