Two-stage revision combined with anti-infective therapy for mixed fungal and bacterial knee periprosthetic joint infection: a case report and literature review.
Review in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFungal periprosthetic joint infection (PJI) is rare and challenging to manage, particularly when complicated by concurrent bacterial infection. Evidence guiding optimal surgical strategies, the role of antifungal-loaded cement spacers, and the duration of systemic antimicrobial therapy remains limited. CASE PRESENTATION: We report a single case of mixed fungal–bacterial knee PJI in a 61-year-old woman following total knee arthroplasty. Multiple intraoperative cultures yielded Candida parapsilosis and Staphylococcus warneri. The patient was treated using a planned two-stage revision strategy. During the first stage, the prosthesis was removed with extensive debridement, and an articulating polymethylmethacrylate (PMMA) spacer loaded with voriconazole and vancomycin was implanted. Systemic intravenous voriconazole and vancomycin were administered for 10 weeks, followed by oral consolidation therapy to a total duration of 12 weeks. Second-stage revision was performed after clinical resolution, normalization of inflammatory markers, and negative intraoperative cultures.
conclusionThis case suggests that a two-stage revision protocol combined with local antifungal and antibacterial delivery and prolonged systemic therapy can be a feasible management option for mixed fungal–bacterial knee PJI. However, conclusions regarding causality or optimal treatment components cannot be inferred from a single case.
