Endoscopic Flexor Hallucis Longus Transfer With Interference Screw and Additional Tension Slide Cortical Button for Chronic Achilles Tendon Rupture.

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: Endoscopic flexor hallucis longus (FHL) tendon transfer can be used in the management of acute or chronic Achilles tendon rupture (ATR), including in elite sportspeople. A recent cadaveric study demonstrated that an increased ultimate load could be applied using an FHL tendon transfer with interference screw and cortical button applied using a tension slide technique compared with interference screw alone. The aim of this study was to explore patient-reported functional outcomes following this modification to this operation. Methods: We reviewed the imaging, history, patient-related outcome measures (PROMs), and complications of 17 patients who underwent endoscopic FHL tendon transfer for chronic ATR using the modified FHL reconstruction technique. The primary outcome was the Manchester-Oxford Foot Questionnaire (MOxFQ), EuroQol-5 Dimensions (EQ-5D), and visual analog score for pain (VAS-Pain) with a mean follow up of 1.5 years. Results: Seventeen patients (11 male, 6 female) underwent endoscopic FHL tendon transfer for chronic ATR between September 2020 and May 2023. Mean (SD) age at the time of surgery was 58.3 (16.1) years, and mean (SD) BMI was 27.6 (4.8). A specific event in the history associated with the rupture was present in 13 of 17 patients (76.5%); the median (IQR) time between injury and surgery was 33 weeks (21-42). Sixteen surgeries were primary procedures for chronic ATR, and 1 surgery was a revision procedure after a failed open acute ATR repair. MOxFQ, EQ-5D, and VAS-pain scores all showed a statistically significant improvement postoperatively (minimum 10 months) when compared to preoperative scores. There was 1 symptomatic complication of tibial neuritis (5.9%). Conclusion: Endoscopic FHL tendon transfer for chronic ATR augmented using a cortical button as well as an interference screw seems to be a safe and effective procedure, with patients reporting a statistically significant improvement in health-related quality of life, pain, and specific foot and ankle outcome function.
