Purpose: to compare suture time and closure quality of a swaged-on needle versus a Controlled Release needle (CR) for a better wound closure to achieve efficient and cosmetically pleasing outcomes.

Methods: Eight midlevel and senior orthopaedic residents performed a seven-centimeter wound closure onporcine skin with both suture types. Closures were timed, and an image was captured on each specimen. Evaluations of images were conducted by threeboard certified orthopaedic surgery faculty on aspects of closure quality and overall pass/fail measures.

Results: Mean time to closure differed significantly by needle type: CR time was 225.7 seconds, 95% CI (205.1, 246.3), whereasswaged was 265.8 seconds, 95% CI (242.3, 289.2); p= 0.011. Interrater agreement showed no statistical difference for closure quality, except forknot visibility where the swaged-ontype had more reports of no knot visualization. Evaluations for pass/fail ratesdid not find statistical difference between needle types.

Conclusions: This study demonstrates that wound closure procedures utilizing controlled release needlesare significantly faster and provides similar outcomes. Future studies should evaluate potential cost savings using this method.
