Closed incision negative pressure therapy may reduce the rate of surgical site complications among higher risk patients undergoing total hip arthroplasty with the direct anterior approach, according to results presented in this study.

In the prospective, multicenter, randomized controlled trial, H. John Cooper, MD, and colleagues randomly assigned 120 patients undergoing THA through the direct anterior approach to receive either a silver impregnated occlusive dressing or a closed incision negative pressure therapy dressing, which was maintained in place for 7 days postoperatively.
