Does Suture Configuration Matter in Achilles Tendon Repairs?
Nathan Benner, Hana Keller, Grant Branam, Scott Telfer, Kenneth Chin

TL;DR
This study finds that a specific suture configuration improves the strength of Achilles tendon repairs in a porcine model.
Contribution
The study introduces a biomechanical comparison of four suture configurations for Achilles tendon repair using a porcine model.
Findings
Double-locked tape suture configuration showed significantly higher load to failure compared to single suture types.
No significant differences were observed in creep tests across suture configurations.
Double tape and double round techniques performed similarly in terms of load-to-failure variables.
Abstract
Background: The human Achilles tendon is functionally important for dynamic activities and is a common site of tendon rupture, resulting in pain, weakness, and removal from sport. While treatment options vary and the opinions regarding optimal management are not uniform, percutaneous repair through commercially available guides is one option that has been used in the United States. Hypothesis/purpose: The purpose of this study was to test the mechanical properties of four common suture configurations in the repair of Achilles tendon ruptures. Study design: This biomechanical study utilized porcine toe flexor tendons as an analogue for the human Achilles tendon. Methods: Simulated rupture was performed, and tendons were repaired using a percutaneous guide. The technique was uniform with predetermined allotment into one of four groups based on suture configuration (single or double…
