Identifying patients at risk in revision arthroplasty: a comprehensive single-centre analysis.
Article in Journal of orthopaedic surgery and research, 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 demand for revision hip and knee arthroplasty (rTHA/rTKA) is increasing, while they continue to be associated with greater perioperative risks, higher resource demands, and greater variability in outcomes compared with primary procedures. Identifying precise risk factors is essential for effective perioperative management and resource planning.
methodsA retrospective analysis of 2,123 revision total hip (rTHA, n = 1,301) and knee arthroplasties (rTKA, n = 822) performed from 2010 to 2019 at a tertiary German centre was conducted. Adverse events (AE), length of hospital stay (LOS), and predictors including age, Elixhauser Comorbidity Index (EI), joint type, and indication were analysed using multivariate regression models.
resultsThe overall AE rate was 13.1%, significantly higher in rTHA than in rTKA (12.6% vs. 8.8%; p = 0.008), particularly for infections and mechanical complications. Mean LOS was 19 ± 14 days. Infection, age, EI, joint type, dislocation, and periprosthetic fracture independently predicted AE and LOS. Infection was the strongest predictor overall (AE: OR 5.4; LOS: Coefficient 1.6), with periprosthetic fractures being highly predictive in rTKA (OR 9.8).
conclusionsInfection (in all revisions), periprosthetic fractures (in rTKA), advanced age, and high comorbidity burden were critical determinants of perioperative adverse events and hospital utilisation. Focused perioperative care strategies targeting these risk groups are essential to mitigate adverse outcomes and optimise healthcare resources.
