Does the duration of antibiotic treatment following one-stage treatment of infected total knee arthroplasty influence the eradication rate? A systematic review.

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
purposeThe aim of this study was to perform a systematic review of the current literature to elucidate the optimal duration of systemic antibiotic therapy following one-stage revision TKA in the setting of PJI.
methodsWe conducted an electronic search in four databases including Medline (PubMed), Scopus, Web of Science, and Cochrane Central Register of Controlled Trials without any publication date, language or study design filter on October 1, 2022. The search strategy adhered to PRISMA guidelines and consisted of four main keywords categories which were knee arthroplasty or knee prosthesis, infection and one-stage/single-stage revision. Duration of antibiotic administration were classified to three groups: short-term IV therapy (≤ two weeks), short-term IV therapy plus oral therapy, and long-term IV therapy (minimum six weeks).
resultsWe identified 963 studies, of which 21 were included in the systematic review. Coagulase-negative Staphylococcal species were the most frequently isolated pathogens. The mean eradication rate for all the studies analyzed was 88.4% (range, 62.5-100%). Short-term IV + long-term oral antibiotic therapy demonstrated significantly higher eradication rate compared to the other two regimens following one-stage revision TKA (p = 0.023) (Table 4). In the ten studies with great than five years of follow-up, this difference was no longer statistically significant. Subgroup analysis of antibiotic-loaded cement (ABLC) usage demonstrated higher eradication rates with short-term IV + long-term oral (92.8%) and long-term IV antibiotics (89.7%) compared to short-term IV antibiotics alone (p = 0.006).
conclusionWe demonstrated that short-term IV antibiotics followed by oral antibiotics had similar eradication rates to long-term IV antibiotics in long-term studies, which were both superior to short-term IV antibiotics alone. Nevertheless, there remains a need for prospective and randomized studies to further elucidate a patient-based protocol for the type and duration of antibiotic use following one-stage PJI treatment of the knee.
