    Abstract:
    Aim: The purpose of this study was to conduct a meta-analysis to systematically compare the clinical outcomes between knee barbed sutures (KBS) and knee traditional sutures (KTS) for wound closure in total knee arthroplasty (TKA). Method: This study retrieved potential academic articles comparing the clinical outcomes between KBS and KTS in TKA from the MEDLINE database, the PubMed database, the EMBASE database and the Cochrane Library. The reference articles for the identified studies were carefully reviewed to ensure that all available documents were represented in the study. Results: A total of 14 articles (eight randomized controlled trials [RCTs], six non-RCTs) were involved in our study. The overall participants of barbed Sutures group were 1255, whereas it was 1247 in the traditional sutures. Our meta-analysis showed that KBS is preferable for wound closure of TKA as its shorter lower total cost (weighted mean difference [WMD] = -276.281, 95% CI = -480.281 to -72.280; p = 0.008) and wound closure time (WMD = -4.895,95% CI = -6.105 to -3.685; p < 0.001). However, there was no difference in any complications (p = 0.572), wound complications (p = 0.550), superficial infection (p = 0.918), deep infection (p = 0.654), wound dehiscence (p = 0.649), suture abscess (p = 0.939), arthrofibrosis (p = 0.970), needle sticks (p = 0.158), suture breakage (p = 0.371) and knee society scores (KSS; p = 0.073). Conclusion: The use of KBS in TKA is associated with significantly shortened wound closure times and total closure cost without increased risk of intraoperative needle sticks and suture breakage and postoperative incision complications. Given the relevant possible biases in our study, adequately powered and more RCTs with long-term follow-up are needed to compare the efficacy and safety between KBS and KTS.
