Outcomes Following Conversion of Ankle Fusion to Transfibular Total Ankle Arthroplasty.

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: Surgical management of failed ankle fusion is challenging. The objective of this study is to present the clinical and radiographic results of tibiotalar fusion takedown via a lateral approach with conversion to transfibular, trabecular metal (TM) total ankle arthroplasty (TAA). Methods: Sixteen patients underwent an ankle fusion takedown with conversion to transfibular TAA: 9 patients had prior tibiotalar fusions, and 7 had tibiotalocalcaneal fusion. Patient demographics, complication profiles, and radiographic parameters were collected. Pre- and postoperative patient-reported outcome measures (PROMs) were analyzed with 12-Item Short Form Health Survey (SF-12), visual analog scale (VAS), and the Ankle Osteoarthritis Scale (AOS). Radiographic outcomes included coronal and sagittal alignment, tibiotalar plantarflexion (PF) and dorsiflexion (DF) range of motion, and incidence of periprosthetic radiolucency and/or implant subsidence. Results: Average age was 56.8 (range, 25-75) years with 4.7 (2-11) years' follow-up. There was significant improvement in VAS, AOS pain and disability, and SF-12 physical and mental component summary scores (all Conclusion: Ankle fusion takedown with conversion to a TM ankle through a transfibular approach yielded significant improvement in PROMs and radiographic ROM, with a modest complication rate at average 4.7 years' follow-up. Although technically challenging, transfibular TAA following ankle fusion takedown is a reasonable treatment option for symptomatic tibiotalar or pantalar fusion. Level of Evidence: Level IV, case series.
