Ultrasound-assisted minimally invasive repair of acute Achilles tendon rupture with a shuttling needle.

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
backgroundThe optimal management of acute Achilles tendon ruptures remains controversial. Open surgical repair (OSR) carries high complication rates, while minimally invasive techniques reduce risks but pose concerns regarding sural nerve injury. This study evaluates the clinical outcomes of ultrasound-assisted minimally invasive repair (MIR) using a double-ended shuttling needle.
methodsA retrospective cohort of 41 patients (2017-2022) was analyzed: 19 underwent OSR (8-10 cm midline incision, Krackow suture), and 22 received MIR (2 cm incision, ultrasound-guided Bunnell suture with shuttling needle). Operative time, scar length, American Orthopaedic Foot & Ankle Society (AOFAS) score, Achilles Tendon Rupture Score (ATRS), calf circumference, and complications were compared. Statistical analyses included independent t-tests, Mann-Whitney U tests, and chi-square tests (α = 0.05).
resultsMIR demonstrated significantly shorter operative time (18.8 ± 3.0 min vs. 55.2 ± 6.5 min; p = 0.010) and smaller scars (2.02 ± 0.39 cm vs. 10.2 ± 1.9 cm; p = 0.005) versus OSR. No significant functional differences existed at 12 months (AOFAS: 90.2 ± 4.3 vs. 88.6 ± 3.8, p = 0.558; ATRS: 90.9 ± 3.3 vs. 89.7 ± 2.6, p = 0.601). Zero complications occurred with MIR, whereas the OSR had 1 superficial infection, 3 sural nerve injuries, and 2 cases of scar adhesion. MIR patients initiated controlled training at 3 months, showing superior trends in activity resumption.
conclusionUltrasound-assisted MIR reduces operative time by 69.9%, minimizes scarring by 80.2%, and eliminates nerve injury risks while achieving functional parity with OSR. Long-term biomechanical performance and resource accessibility warrant further investigation.
