Pseudotumor in total knee revision arthroplasty resembling heterotopic ossification: A case report.
Article in International journal of surgery case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionPseudotumors are well-known complications following total hip arthroplasty (THA), usually attributed to debris-induced inflammation from direct metal-on-metal contact between implants. In total knee arthroplasty (TKA), the traditional use of polyethylene as a bearing surface prevents direct metal articulation. Thus, pseudotumor formation in TKA usually suggests atypical metal interaction between the prosthetic components. PRESENTATION OF CASE: We presented the case of a 65-year-old male who developed a progressively growing mass in the left posterior knee after revision TKA, debuting as heterotopic ossification (HO) based on the radiographic assessment. Subsequent histopathological examination establishes the diagnosis of a pseudotumor. DISCUSSION: Pseudotumors impose a diagnostic challenge in TKA due to their non-specific presentation and imaging, which may overlap with other etiologies. Currently, there are no standardized guidelines for pseudotumor assessment in TKA, and each case should be approached individually without relying on a simple diagnostic tool.
conclusionPhysicians should consider a comprehensive approach supported by a high index of suspicion to include pseudotumors within the differential diagnosis of knee periprosthetic masses.
