Abstract
IntroductionPeri-prosthetic joint infection (PJI) was one of the main causes of revision of arthroplasty. In order to reduce wound complications and surgical site infections, close incisional negative pressure wound therapy (ciNPWT) has been introduced into arthroplasty. This study was designed to review the clinical benefits of the application of ciNPWT in revision arthroplasty.MethodsThis was a single-centre retrospective comparative study approved by the Institutional Review Board. Patients, who underwent revision total knee arthroplasty or revision total hip arthroplasty at the author’s institution from January 2016 to October 2019, were included in this study. The ciNPWT cohort included all eligible patients, who underwent operations from January 2018 to October 2019, with the use of ciNPWT(n = 36). The control cohort included all eligible patients, who underwent operations from January 2016 to December 2017 with the use of conventional dressing(n = 48). The incidences of wound complications were compared to both cohorts.ResultsThere was a statistically significant difference in the rate of superficial surgical site infection (SSI) between control cohort and ciNPWT cohort (12.5% in control vs 0% in ciNPWT, p = 0.035). However, there was no statistically significance of the overall wound complication rate for both cohorts. (14.6% in control vs 8.3% in ciNPWT, p = 0.504).ConclusionsThe application of ciNPWT could result in a lower rate of superficial surgical site infection when compared with conventional dressing among the patients undergoing revision total knee and total hip arthroplasties.Trial registrationUW19-706

Peri-prosthetic joint infection (PJI) was one of the main causes of revision of arthroplasty
This study aimed to review the efficacy of the application of close incisional negative pressure wound therapy (ciNPWT) in revision arthroplasty when compared with conventional dressing in the authors’ institution, which is one of the major joint replacement centres in Asia
36 patients were enrolled in the ciNPWT cohort and 48 patients in the control cohort
Summary
Peri-prosthetic joint infection (PJI) was one of the main causes of revision of arthroplasty. In order to reduce wound complications and surgical site infections, close incisional negative pressure wound therapy (ciNPWT) has been introduced into arthroplasty. This study was designed to review the clinical benefits of the application of ciNPWT in revision arthroplasty. Complications to wound healing can be detrimental to the clinical outcomes after arthroplasty. It can lead to major complications including infection and need for subsequent surgery. Chan et al Arthroplasty (2021) 3:38 in postoperative complications rates relative to primary knee arthroplasty [3]. Various measures were advocated to optimize wound healing after arthroplasty. These included preoperative optimization of modifiable risk factors such as nutritional status, smoking status, and diabetic control. Advanced dressing management is another important area, which has recently got more attention as more scientific evidence proven it clinical effectiveness in arthroplasty
