DVIA technique for acute periprosthetic joint infection: a surgical technique and case series.
Article in Arthroplasty (London, England), 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
aimsPeriprosthetic joint infection (PJI) remains a major challenge in orthopaedic surgery. While debridement, antibiotics, and implant retention (DAIR) are a common treatment for acute PJI, its success rate is variable. Intra-articular antibiotic administration and wound healing techniques may enhance infection control and improve clinical outcomes. This study aimed to describe a modified technique combining DAIR with vacuum sealing drainage (VSD) and intra-articular antibiotic infusion (DVIA) for treating acute PJI, and evaluate its clinical feasibility and preliminary outcomes.
methodsThis retrospective, single-center case series included 31 patients who underwent DVIA (hip: 19; knee: 12) between September 2019 and December 2023. Following DAIR, a technique integrating vacuum-sealed drainage for wound management with intra-articular antibiotic infusion was applied. Inflammatory markers (CRP, ESR) and intra-articular antibiotic concentrations were monitored at multiple time points. Treatment outcomes, CRP and ESR levels, Knee Society Score (KSS), KSS functional score, Harris Hip Score (HHS), and the 36-item Short-Form (SF-36) physical function scale were evaluated over a 12-month follow-up.
resultsInfection control was achieved in 90.32% (28/31) of patients. CRP and ESR levels decreased after treatment. Joint function and patient-reported physical function improved during follow-up. Intra-articular vancomycin concentrations measured in a subset of patients exceeded previously reported minimum biofilm eradication concentration (MBEC) thresholds. No catheter-related complications, retrograde infections, or systemic antibiotic-related adverse events were observed.
conclusionThe DVIA technique appears to be a feasible adjunctive strategy for the management of acute PJI, enabling effective local antibiotic delivery and favorable clinical outcomes. These findings are preliminary and warrant further validation in prospective controlled studies.
