Severity of Achilles Tendinopathy on Preoperative MRI and Short-term Functional Outcomes After Minimally Invasive Zadek Osteotomy.
Article in Foot & ankle orthopaedics, 2025. 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
Background: Limited literature is available to guide surgeons on which patients with insertional Achilles tendinopathy (IAT) may be the best candidates for minimally invasive dorsal closing wedge calcaneal Zadek osteotomy (MIS ZO). We hypothesized that the severity of IAT on preoperative magnetic resonance image (MRI) may correlate with post-operative functional outcomes and help guide patient selection for treatment with MIS ZO. Methods: Patients who underwent MIS ZO for IAT ± Haglund deformity were identified and retrospectively analyzed. IAT severity was graded on preoperative MRI. Patient Reported Outcome Measurement Information System (PROMIS) scores, complications, and revisions were recorded. Continuous data were compared by analysis of variance with Bonferroni post hoc analysis. Results: Seventeen patients treated with MIS ZO, with follow-up >6 months, and preoperative MRI met our inclusion criteria. PROMIS pain scores significantly improved in patients with IAT grades 1-3, with 5, 5, and 7 patients, respectively, in each subgroup. In this small series we only identified statistically significant improvements in PROMIS function ( Conclusion: In this pilot study, we did not find preoperative MRI findings to correlate well with patient-reported outcome scores following MIS ZO. Level of Evidence: Level IV, case series.
