Effect of barbed versus standard sutures on wound complications in total knee arthroplasty: A meta‐analysis

A barbed suture has been demonstrated to be effective in shortening the stitching time and improving the aesthetic appearance of the stitches during the entire knee replacement. However, no meta‐analyses have been conducted specifically to evaluate the effect of the barbed thread on wound complications relative to the conventional suture. A comprehensive search of the PubMed database, the Embase database, the Cochrane Library and the Web of Science was performed to obtain search data up to June 2023, and only randomised controlled trials were included in this meta‐analysis. We used Review Manager 5.3 for data synthesis and analysis. This meta‐analysis included eight studies. It was found that the use of barbed sutures did not improve the incidence of the disease, the infection of the wound, the closure of the abscess and the injury. However, because of the limited sample size of the randomised controlled trials for this meta‐analysis, the data should be handled with caution. More high‐quality, large‐sample studies will be required to confirm the results.
