Association of Dementia With Total Ankle Arthroplasty and Ankle Arthrodesis Outcomes: A Short Report.
Article in Foot & ankle orthopaedics, 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
Background: Foot and ankle surgeons evaluate older patients with ankle arthritis and dementia. In this report, we analyzed postoperative complications following ankle arthrodesis (AA) and total ankle arthroplasty (TAA), hypothesizing greater risk in patients with dementia. Methods: We conducted a retrospective cohort study using Medicare claims from 2016 to 2021, including beneficiaries aged ≥65 years who underwent TAA or AA. The primary independent variable was dementia, defined using the Charlson Comorbidity Index (CCI) dementia component based on Results: Dementia was present in 0.56% of TAA patients (73 of 13 134) and 3.6% of AA patients (308 of 8519). With the numbers available, no significant differences could be detected with dementia in TAA using adjusted multivariable analyses, although 12-month readmissions were higher ( Conclusion: We found differences in postoperative outcomes, particularly readmissions and mortality, in patients with dementia following AA. Conversely, we found limited differences in patients with and without dementia undergoing TAA, which may reflect limited power to detect modest differences given the smaller number of dementia patients in the TAA cohort. Further research should explore how the severity of cognitive impairment influences decision making in ankle arthritis treatment. Level of Evidence: Level III, retrospective cohort study.
