Kidney Injury and Mortality Are Minimal Following Two-Stage Treatment of Periprosthetic Joint Infection.
Article in The Journal of arthroplasty, 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
backgroundThe current gold standard treatment for chronic periprosthetic joint infection (PJI) is a two-stage surgery with antibiotics between implant resection and reimplantation. Recently, claims have been reported of nephrotoxic antibiotic exposure and acute kidney injury (AKI) during the two-stage PJI treatment. This study evaluated kidney function and mortality before, during, and after two-stage revisions for PJI using a standardized protocol.
methodsClinical data from 138 hips and knees undergoing two-stage treatment for PJI were retrospectively reviewed. Standardized perioperative clinical protocols were used for all patients, including hypotensive anesthesia and tranexamic acid to minimize operative blood loss, aggressive fluid resuscitation, medical optimization, and six weeks of intravenous antibiotics prior to reimplantation. The incidence of AKI, serum creatinine, estimated glomerular filtration rate, blood urea nitrogen, and overall mortality were collected from a statewide healthcare system. P-values ≤ 0.05 were considered statistically significant.
resultsOverall, the incidence of AKI was 9.4% (13 of 138), which was 4.3% in patients who did not have preexisting kidney disease. There were no significant differences observed in mean serum creatinine (1.10, 1.12, 1.13 mg/dL), estimated glomerular filtration rate (78.6, 77.7, 74.8 mL/minute/1.73 m
conclusionsIn this single-institution series using a standardized protocol, mean kidney function metrics remained relatively stable throughout the two-stage treatment. Furthermore, mortality after the two-stage approach was negligible and unlikely to be associated with the treatment itself. Still, comparative studies of the one-stage technique remain warranted. LEVEL OF EVIDENCE: III.
