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.
