简要总结
The purpose of this study is to determine the efficacy of a negative pressure wound therapy (NPWT) system after revision total knee and hip arthroplasty in patients at high risk for infection. It is hypothesized that the use of NPWT system (i.e., Prevena) in high risk patients prevents wound complications and decreases reoperation rates.
详细描述
One of the primary causes of un-planned readmission following lower extremity arthroplasty procedures is infection. Continuous wound drainage poses a serious risk for infection and is often initially treated with absorbent dressings and/or oral antibiotics. Comorbidities such as obesity, diabetes and tobacco abuse predisposes to wound complications and therefore infection after these procedures. NPWT has proven to be effective for postoperative drainage and decreases the risk for infection or further reoperation. This prospective randomized trial will involve 160 patients at high risk for infection undergoing revision total knee or hip arthroplasty; 80 patients will be randomly selected to be treated with the NPWT system (Prevena) and randomly selected to be treated with the current standard of care wound dressing (control group). Patients will be enrolled at a single site of the Cleveland Clinic Health System (Main Campus).
