Biomechanical comparison of the primary stability of suturing Achilles tendon rupture: a cadaver study of Bunnell and Kessler techniques under cyclic loading conditions

Abstract

In our study Bunnell and Kessler techniques showed similar biomechanical properties using the same suture material. The typical failure mode of the Bunnell technique shows potential to optimise biomechanical behavior by using stronger suture material.

Initial stability of two different adhesives compared to suture repair for acute Achilles tendon rupture—A biomechanical evaluation

“…However, based on the active components these factors should not be of significant influence. Since the presented biomechanical properties after suture repair are comparable to previous studies, the use of sheep tendons in our study does not appear to bias the data significantly [19,21,31].…”

“…For this purpose gluing techniques need to provide initial biomechanical properties comparable to those of suture repair. In a biomechanical study comparing initial stability of different suture techniques, Watson et [21].…”

“…This technique offers high stability by providing a large contact area between the tendon and suture material and is considered a standard technique for open Achilles tendon repair [19][20][21][22][23].…”

A biomechanical comparison of the primary stability of two minimally invasive techniques for repair of ruptured Achilles tendon

“…Furthermore, no univocal results have been obtained when comparing the Kessler and the Bunnel configurations. In fact, in other biomechanical studies, the locking loop configuration was substantially stronger that the Kessler and the Bunnel configurations, while the latter two did not differ significantly each other [13,47].…”

Surgical Technique: When to Arthroscopically Repair the Torn Posterior Cruciate Ligament

“…Most importantly, newer, reloadable suture passing devices and improved arthroscopic equipment enable the passage of more complex, Bunnell-type stitch patterns through the PCL stump. The Bunnell stitch has a higher maximum load to failure force than the Kessler stitch [11,26] and certainly more than simple sutures. The Bunnell stitch is complimented by using modern suture material of increased strength.…”
