Wear or failure of the acetabular bearing component is still a main reason for revision surgery. In many situations, the femoral stem and/or acetabular cup components are well fixed in the bone and only the bearing surfaces require exchange. Damage to the implants remaining in the body caused by loading in the patient before the revision surgery or inflicted during revision surgery can have major consequences for the longevity of the implants.
Since the removal of a well ingrown implant is a big burden for the patient, an attempt should be made to keep the implants in situ. In the presentation several damage modes will be presented and suggestions made on how to deal with them, how to prevent further damage during revision surgery, and how to prevent consecutive failure. Issues addressed include taper corrosion, ceramic fracture, spark discharge from electrosurgical tools, notching, mismatch, and offset.
