Beyond Early Complications: Diabetic Neuropathy Is Associated With Progressive Failure, Reoperation, and Mortality After Ankle Arthrodesis.
Article in Orthopedic reviews, 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: Diabetic peripheral neuropathy may affect outcomes after ankle arthrodesis, but its specific impact on infection, mechanical failure, reoperation, mortality, and healthcare utilization after ankle arthrodesis remains incompletely defined. This study compared postoperative complications, reoperations, and healthcare use after ankle arthrodesis in diabetic patients with and without neuropathy. Methods: A retrospective cohort study was performed using the TriNetX Research Network, a multicenter federated electronic health record database. The analysis conducted included patients from January 2020 to January 2025. Adult diabetic patients undergoing primary ankle arthrodesis for osteoarthritis were identified and stratified by the presence or absence of preoperative diabetic peripheral neuropathy. After 1:1 propensity score matching, 731 patients were in each group. Outcomes at 1, 3, and 5 years included mechanical failure, revision arthrodesis, subsequent ankle surgery, postoperative infection, mortality, and emergency department use. Results: Patients with diabetic peripheral neuropathy experienced a consistently greater postoperative complication burden following ankle arthrodesis compared with diabetic patients without neuropathy. Across short-, intermediate-, and long-term follow-up, neuropathy was associated with significantly higher rates of postoperative infection, mechanical failure, and emergency department utilization. At longer-term follow-up, patients with neuropathy also demonstrated greater rates of revision arthrodesis, subsequent ankle surgery, and mortality. Differences in venous thromboembolism and myocardial infarction were not significant between groups. Conclusions: Diabetic peripheral neuropathy was associated with increased complications, reoperation, healthcare utilization, and long-term morbidity after ankle arthrodesis. It should be recognized as a key risk factor in perioperative planning, patient counseling, and postoperative surveillance.
