This retrospective study of 106 periprosthetic hip infections in 97 patients evaluates treatment outcomes across four clinically defined infection categories — positive intraoperative cultures, early postoperative, late chronic, and acute hematogenous — and asks whether classifying infection by clinical presentation guides treatment selection and predicts success.
When you encounter a THA infection, map it to the Tsukayama category first: the clinical timeline and acuity drive both the operative strategy (retain vs. Two-stage exchange) and empiric antibiotic selection — and if the early postoperative prosthesis is cementless, the data strongly favor removal at the index debridement rather than retention.
