Comparison of Negative Pressure Wound Therapy vs. Conventional Dressings for Prevention of Wound Complications After Revision THA

Wound complications and surgical site infections following revision total joint arthroplasty result in significant morbidity and cost. To the investigators knowledge, no prospective, randomized controlled trials have examined the rate of wound complications, infection, and reoperation following revision total hip arthroplasty when treated with negative pressure wound therapy (NPWT) versus sterile dressings. The investigators hypothesize that the rate of wound complications, infections, and subsequent procedures in patients undergoing revision THA treatment will demonstrate a statistically and clinically relevant decrease when using NPWT versus sterile dressing.

Wound complications and surgical site infections (SSI) following revision total joint arthroplasty result in significant morbidity and cost. Persistent incisional drainage following total joint arthroplasty (TJA) has been reported to occur in 1% to 3% of patients. Drainage persisting greater than 48 hours has been reported as a risk factor for the development of an acute periprosthetic joint infection (PJI), with each additional day of wound drainage increasing the infection risk by 29-42%. Consequently, continued wound drainage has been shown to potentially increase the economic burden through longer hospital stays and subsequent surgical procedures. To the investigators knowledge, no prospective, randomized controlled trials have examined the rate of wound complications, infection, and reoperation following revision total hip arthroplasty when treated with NPWT versus sterile dressings. The investigators hypothesize that the rate of wound complications, infections, and subsequent procedures in patients undergoing revision THA treatment will demonstrate a statistically and clinically relevant decrease when using NPWT versus sterile dressing. The investigators will utilize a prospective, randomized, controlled study design to assess the efficacy of negative pressure wound therapy (NPWT) on the rate of wound complications, surgical site infections (SSIs), and reoperations after revision total hip arthroplasty (THA). For 90 days after surgery, the wound complications, including wound dehiscence, prolonged drainage for \>7 days postoperatively, hematoma formation, surgical site infection, or periprosthetic joint infection that requires postoperative interventions, and reoperation will be tracked.
