Summary
The purpose of this study is to determine whether an occlusive antimicrobial barrier dressing or portable negative pressure wound dressing is superior in preventing wound complications and infection rates in obese patients undergoing total joint arthroplasty (TJA). Approximately 240 subjects (120 for total knee arthroplasty and 120 for total hip arthroplasty) will be enrolled to evaluate the outcomes associated with silver impregnated dressings and negative pressure wound therapy (NPWT) in treating this subset of patients and analyze the cost benefit of each.
