Ultrasound-guided Achilles tendon rupture repair using knotless barbed suture: a cadaveric study.

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
purposeTo describe a novel, minimally invasive, ultrasound-guided Achilles tendon repair technique using a knotless barbed suture and to assess its feasibility in a cadaveric model.
methodsA midportion Achilles tendon rupture was simulated in a Thiel-embalmed cadaver. The tendon was repaired percutaneously under ultrasound guidance using a 0.6-mm USP 1 knotless barbed suture mounted on a 19-gauge, 3.5-inch curved needle. The needle was advanced intratendinously under continuous ultrasound guidance. Tendon reapproximation was assessed with ultrasound and confirmed by anatomical dissection. The resting plantar flexion angle was measured before and after the repair.
resultsThe Achilles tendon repair technique resulted in successful reapproximation of the tendon ends with anatomic alignment. Post-repair ultrasound and dissection confirmed accurate intratendinous suture placement and full tendon continuity. The resting plantar flexion angle increased from 23° to 50° after the repair.
conclusionThis is the first report of an ultrasound-guided Achilles tendon repair using a knotless barbed suture. The technique appears feasible in a cadaveric model and may represent a promising minimally invasive option for patients requiring improved tendon approximation. Its office-based approach may reduce surgical risks associated with conventional repair and tendon elongation seen with conservative treatment. Further biomechanical and clinical studies are warranted to evaluate its safety, durability, and functional outcomes.
