Introduction: Early mobilization of a repaired deep exor tendon promotes better outcomes than immobilization. Tension on the reconstruction, however, produces gap formation at the repair site, which is detrimental. The changes in the 3-dimensional suture geometry when a tendon repair is strained, and the relationship this has to gap formation have not clearly been characterized yet. Therefore, we present a novel X-ray technique to qualitatively and quantitatively examine the three-dimensional changes in the core suture repair con gurations under tension.
Introduction: Current literature suggests that the cross locked cruciate repair not only provides a good compromise between complexity and nal failure force, but also is a favorable repair in terms of gap formation. In this study we modi ed this repair con guration by interlocking its distal components to further improve gapping propensities. Additionally we introduce a new tendon repair technique: The threedimensional knotless barbed suture tenorrhaphy. Aim of this study was to compare these two new tendon repair methods with the conventional cross locked cruciate repair in a dynamic testing scenario, focusing on maximum load capacity and gap formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
