Comparison between Zip-Type Skin Closure Device and Staple for Total Knee Arthroplasty: A Meta-Analysis

PURPOSE: To compare the efficacy and safety of zip-type skin closure device (SCD) and staple in total knee arthroplasty (TKA). METHODS: Potential academic articles were identified from PubMed, Springer, ScienceDirect, and Cochrane Library from the inception of electronic databases to July 2020. The statistical analyses were performed with RevMan 5.1. RESULTS: One randomized controlled trial (RCT) and 5 non-RCTs met the inclusion criteria. Present meta-analysis reveals that SCD is associated with lower wound pain score, scar score, and readmission compared with a staple. No significant differences are identified in terms of wound total complications, dehiscence, blisters, and infection. CONCLUSIONS: Comparing with a staple, zip-type SCD is a less painful skin closure method with fewer medical cost undergoing TKA.
