Total hip replacement involves the removal of damaged cartilage and bone from the hip joint, which are then replaced with artificial components. In some cases, hip replacement implants may wear out due to various reasons and require a surgical procedure called revision hip replacement surgery.Revision hip replacement is a complex surgery that involves replacing all or part of a previously implanted hip joint with a new artificial hip joint. Total hip replacement is an effective option to relieve severe arthritis pain that limits daily activities. Patients should be aware of the possibility of revision hip replacement and discuss this with their healthcare provider.
Revision hip replacement is advised for the following conditions:
During a revision hip replacement surgery, the patient will be given general anaesthesia to induce sleep. Then, the surgeon will make an incision over the hip joint to access it. The femur bone will be dislocated from the acetabulum to remove the old plastic liner and metal socket from the joint.
After that, additional bone and wire mesh will be used to fill in any gaps or irregularities in the acetabulum's shape. Then, the new metal shell will be inserted into the socket using screws or a special cement. A liner made of plastic, ceramic, or metal will be placed inside the metal socket. To prepare the femoral component, the top of the femur bone will be cut into several pieces to remove the old implant. The bone segments will be cleaned, and the new femoral implant will be inserted into the femur either through a press fit or by using bone cement. Surgical wires will be used to hold the bone segments and the femoral component together. Finally, the femoral head component, made of metal or ceramic, will be placed onto the femoral stem. All new components will be secured in place to form the new hip joint. The muscles and tendons surrounding the new joint will be repaired, and the incision will be closed.
