Midterm Results of Large-Caliber Tendon Allografting for Chronic Achilles Tendon Rupture With Large Defects.

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: Chronic Achilles tendon ruptures with large defects present a considerable challenge in treatment. Purpose: This study evaluated the midterm outcomes of fresh-frozen large-caliber allograft reconstruction for chronic Achilles tendon ruptures. Study Design: Case series; Level of evidence, 4. Methods: A total of 32 patients (18 women and 14 men), with a mean age of 57.6 years (range, 21-81 years), were enrolled between 2007 and 2021. Of 32 ankles, 21 and 11 defects involved Achilles tendon ruptures at the middle and distal sections, respectively. The mean ruptured gap was 5.8 cm (range, 5-10 cm), and the mean follow-up period was 8.4 years (range, 3-16.9 years). The American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, visual analog scale (VAS) score, and Achilles Tendon Total Rupture Score (ATRS) were used to evaluate the outcomes. Results: The patients' AOFAS ankle-hindfoot score increased from 64.8 ± 10.8 to 95.4 ± 4.2 ( Conclusion: Our midterm results revealed that fresh-frozen large-caliber tendon allografts represent a reasonable option for treating chronic Achilles tendon ruptures with large defects, achieving acceptable outcomes.
