The surgical procedure for your hip arthroplasty revision will be explained to you prior to surgery including what is likely to be done. However, with revision surgery the unexpected can occur and good planning can prevent most potential problems. The surgery can be, but not always, more extensive than your previous surgery and the complications are similar but often more frequent than the first operation.
The surgery varies from a simple liner exchange to changing one or all of the components. Extra bone (cadaver bone) may need to be used to make up for any bone loss.
