title: Barbed versus standard sutures for closure in total knee arthroplasty: a multicenter prospective randomized trial.
abstract: Barbed suture has been associated with improved closure efficiency and safety in TKA in prior studies. We performed a multicenter randomized controlled trial to determine the efficiency and safety of this technology in TKA. We prospectively randomized 411 patients undergoing primary TKA to either barbed running (n=191) or knotted interrupted suture closure (n=203). Closure time was measured intra-operatively. Cost analysis was based on suture and OR time costs. Closure time was shorter with barbed suture (9.8 vs. 14.5 min, p<0.001). Total closure cost was less with barbed suture ($324 vs. $419, p<0.001). Early complications and outcomes were similar between groups. The use of barbed suture in TKA is associated with shorter closure time, lower cost and similar outcomes and complications when compared with standard sutures.
