My father had a joint replacement that got infected. The doctor is talking about doing a "total revision." What does this mean?

Total revision can have different meanings for each doctor and each patient. You'll need to ask the doctor for a more complete description.

Usually major or total revision means removing or replacing the main part (or all) of the implant. Sometimes a new implant is put in place of the failed one.

In the case of infection with major bone loss, the joint may have to be fused.
