Revision knee arthroplasty is conducted more frequently in our day, due to the increasing number of primary knee arthroplasty. Periprosthetic joint infections, in particular, are still one of the major problems of revision knee arthroplasty.

In appropriate cases, single-stage revision knee arthroplasty after a good preoperative planning can lead to quite successful outcomes.
