 Running knotless suture technique utilizing barbed suture technology has recently been shown to reduce wound closure time in both total hip and knee arthroplasty in a small, prospective, randomized clinical trial. Barbed suture technology has also facilitated rapid closure and soft-tissue repair in plastic-surgery literature. Very few studies have reported on the use of barbed suture technology for multilayered closure in orthopedics. As a pilot study, the investigators performed a retrospective analysis of consecutive cohorts before and after changing to barbed suture. The investigators believed that our published slight improvement in efficiency and cost savings of a barbed suture closure was underestimated due to the retrospective nature of our pilot study and the investigators therefore elected to proceed forward with a prospective randomized trial. Additionally, in the investigators pilot study we found a potential trend toward lower wound complications with the barbed suture and we wanted to see if this would be borne out in a prospective randomized trial.
