Comparison of the Efficacy Between Closed Incisional Negative-Pressure Wound Therapy and Conventional Wound Management After Total Hip and Knee Arthroplasties: A Systematic Review and Meta-Analysis
Kim, Jun-Ho et al.Hip Knee
Background
Wound-related problems after total hip arthroplasty (THA) and total knee arthroplasty (TKA) can cause periprosthetic joint infections. We sought to evaluate the effect of closed incisional negative-pressure wound therapy (ciNPWT) on wound complications, skin blisters, surgical site infections (SSIs), reoperations, and length of hospitalization (LOH).
Methods
Studies comparing ciNPWT with conventional dressings following THA and TKA were systematically searched on MEDLINE, Embase, and the Cochrane Library. Two reviewers performed the study selection, risk of bias assessment, and data extraction. Funnel plots were employed to evaluate publication bias and forest plots to analyze pooled data.
Results
Twelve studies were included herein. The odds ratios (ORs) for wound complications and SSIs indicated a lack of publication bias. ciNPWT showed significantly lower risks of wound complication (OR, 0.44; 95% confidence interval [CI], 0.22-0.9; P = .027) and SSI (OR, 0.39; 95% CI, 0.23-0.68; P < .001) than did conventional dressings. ciNPWT also yielded a significantly lower reoperation rate (OR, 0.38; 95% CI, 0.21-0.69; P = .001) and shorter LOH (mean difference, 0.41 days; 95% CI, −0.51 to −0.32; P < .001). However, the rate of skin blisters was higher in ciNPWT (OR, 4.44; 95% CI, 2.24-8.79; P < .001).
Conclusion
Although skin blisters were more likely to develop in ciNPWT, the risks of wound complication, SSI, reoperation, and longer LOH decreased in ciNPWT compared with those in conventional dressings. This finding could alleviate the potential concerns regarding wound-related problems after THA and TKA.
