Abstract
Periprosthetic joint infection represents a serious complication following total knee
arthroplasty. In the setting of chronic or age-indeterminate total knee arthroplasty
infection, a 2-staged approach has been traditionally the preferred method of treatment
over single-stage debridement and reimplantation debridement or debridement, antibiotics
and implant retention. Two-stage is the preferred treatment method in North America
and has demonstrated better overall success than the single stage techniques. Additionally,
the 2-stage method is the preferred treatment for difficult to treat pathogens as
well as in patients who have already undergone a previous revision procedure. An articulating
prefabricated antibiotic spacer has entered the armamentarium of 2-stage revision
knee surgery, and has demonstrated comparable results to custom and static spacers
in terms of the primary goal of infection control. Importantly, the potential for
enhanced mobility and function hold promise by safely providing a more “livable” knee
during the convalescent period prior to definitive reimplantation.
