Electromagnetic induction disinfection applied to cemented knee arthroplasty implants: safety evaluation of potential changes in the bone cement.
Article in Journal of materials science. Materials in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundElectromagnetic induction heating is a newly developed disinfection method aimed at improving periprosthetic infection outcomes after Debridement and Implant Retention (DAIR). One safety concern is its effect over polymethylmethacrylate (PMMA). The objective of this in-vitro study is to assess such effect on cement adjacent to metallic arthroplasty components.
methodsTwo different PMMA products, with and without antibiotic, were applied on three total-knee arthroplasty implants. A portable device was used to administer induction-heating protocols: 70 °C, 3.5 min and 100 °C, 3.5 min, while the third prosthesis served as control. The 602 cm
resultsIsotactic/syndiotactic ratios were 0.27(±0.02) for antibiotic-free cement, and 0.41(±0.02) for gentamicin-loaded cement. After induction-heating protocols, isotactic fraction increased in antibiotic-free cement, and decreased in gentamicin-loaded cement. No evidence of crystallization was found in ATR-FTIR, except for a small increase in 1340 cm
conclusionsSpectroscopic techniques confirmed that PMMA only experienced minor structural changes after induction heating treatments. From a structural viewpoint, these results suggest that electromagnetic induction heating could be a safe disinfection technique for cemented implants in total knee arthroplasty.
