Short summary
This retrospective study compared debridement and implant retention failure for three types of acute knee replacement infection and analyzed outcomes for patients in a cohort with low medical risk. No differences in failure rate were seen between types in the overall sample or “optimal” cohort. Staphylococcus aureus was less common in later infection, while Streptococcus was less frequent in earlier infection. In an optimal patient, similar outcomes between types may suggest that medical factors do not alter risk.
