Bunnell or cross-lock Bunnell suture for tendon repair? Defining the biomechanical role of suture pretension

Abstract

Based on these results, suture pretension decreases gapping and elongation after tendon repair, and those effects are stronger when using a cross-lock, rather than a regular Bunnell suture. However, pretension causes an unfavorable increase in the tendon diameter at the repair site, which may adversely affect wound healing.
