[Efficacy and safety of barbed sutures in total hip arthroplasty and total knee arthroplasty: a meta-analysis].

To appraise the clinical outcomes of barbed suture in closure of total hip and total knee arthroplasty. Databases (Web of Science, Embase, PubMed, Cochrane Controlled Trials Register,Cochrane Library,Highwire,China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI),VIP and Wanfang database) were searched for randomized controlled trials comparing barbed sutures and conventional sutures in total hip and total knee arthroplasty published before January, 2019. Finally, 11 articles (12 randomized controlled trials) involving 1 629 hips or knees were included in this study. The meta-analysis was performed using the Review Manager software. Compared with conventional sutures,barbed sutures resulted in shorter total wound closure time (0.001), less ecchymosis and needle prick (both 0.05).There was no significant differences in terms of wound related complications, superficial infection, stitch abscess, blister, exudation, broken sutures, range of motionand KSS between barbed sutures and conventional sutures(all 0.05). Based on available level Ⅰ evidence, it indicated that knotless barbed suture maybe a better approach for wound closure in total hip and total knee arthroplasty.
