Prognosis after one- and two-stage revision surgery for periprosthetic joint infection: A systematic review and meta-analysis

OBJECTIVE: Revision surgeries for periprosthetic joint infections (PJIs) in arthroplasty can follow either one- or two-stage treatment protocols. Previous studies have reported similar reinfection rates and reductions in complication rates for both treatment options. However, the literature on the selection of one protocol is still controversial. Thus, our aim was to compare the outcomes, including reinfections, complications, reoperations, and mortality, associated with one- and two-stage revision surgeries for PJI via a systematic review and meta-analysis of comparative studies. METHODS: Comparative studies were identified through searches in PubMed, EMBASE, the Web of Science, and the Cochrane Library as of November 2023. RevMan version 5.3 was used for the analyses. The included studies directly compared one-stage revisions with two-stage revisions for PJI. The primary outcomes included reinfection, complications, reoperation, and mortality. RESULTS: = 0%). CONCLUSIONS: Among the available observational studies, the meta-analysis revealed a lower incidence of reinfection and complications in the one-stage group than in the two-stage group, but there were no significant differences in reoperation events or mortalities.
