A Comparison of Radiographic Alignment Using Patient-Specific and Standard Instrumentation in Total Ankle Arthroplasty.
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: The rate of total ankle arthroplasty (TAA) is projected to continue increasing. Implant malalignment is a significant predictor of complications; however intraoperative evaluation of alignment can be challenging. Patient-specific instrumentation (PSI) was designed to improve implant positioning in TAA. This study compares radiographic alignment and postoperative function in patients who underwent TAA with PSI with an Infinity implant vs standard instrumentation (SI) with a Salto Talaris implant. Methods: We retrospectively reviewed 114 TAA cases using PSI compared with 80 TAA surgeries using SI. Demographics, radiographic alignment, range of motion (ROM), complications, and postoperative American Orthopaedic Foot & Ankle Society (AOFAS) pain, function, and alignment scores were compared at a minimum 1-year follow-up. Results: The PSI cohort demonstrated significantly better radiographic alignment, particularly in tibial component positioning, and reduced frequency of lucencies compared with the SI cohort. However, operative time was significantly longer in the PSI group (mean 119.0 ± 34.5 vs 96.3 ± 26.0 minutes; Conclusion: In this study, PSI was associated with modest differences in tibial alignment and early radiographic lucencies compared with SI, without clear significant differences in short-term clinical outcomes. Both cohorts had similar postoperative range of motion and AOFAS scores. Given the retrospective design and short follow-up, further investigation is needed to assess long-term clinical impact and implant survivorship. Level of Evidence: Level III, retrospective comparative study.
