About this study

Official title: Randomized Controlled Trial of Wound Management With Negative Pressure Dressing Versus Standard Dressing After Knee and Hip Revision Arthroplasty.

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.

Read the detailed description

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).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Wound Complications

    Any wound complications including but not limited to drainage, blisters, cellulitis, superficial infection, and deep infection.

    Measured: Within 90 days after surgery

  2. Re-operation Rates

    Number of patients who required re-operations that were related to the revision arthroplasty and occurred within 90 days of the revision

    Measured: Within 90 days after surgery

  3. Readmission Rates

    Number of patients who had hospital readmission(s) related to the revision surgery that occurred within 90 days of revision

    Measured: Within 90 days after surgery

Secondary outcomes (7)
  1. Knee Flexion

    Mean knee flexion (degrees) at 4 weeks postoperatively

    Measured: 4 weeks postoperative

  2. HOOS and KOOS Scores at 90 Days Postoperatively

    Mean Hip Osteoarthritis Outcome Score (HOOS), Knee Osteoarthritis Outcomes Score (KOOS) at 90 days postoperatively. Presented as subscores, including activities of daily living (ADL), pain, quality of life (QOL), symptoms, sports and recreation. All subscores range from 0-100, with 0 being the worst score and 100 being the best possible score.

    Measured: 90 days postoperative

  3. Timed-up-and-go Test

    Median Timed-up-and-go test (seconds)

    Measured: 4 weeks postoperatively

  4. Hip Range of Motion (Flexion)

    Mean hip range of motion (flexion, in degrees) at 4 weeks postoperatively

    Measured: 4 weeks postoperative

  5. VR-12 Questionnaire

    Mean VR-12 scores, presented as 2 composite scores physical component summary (PCS) and mental component summary (MCS). Physical Component Score (PCS): Provides greater emphasis on questions about general health, physical functioning and role playing and bodily pain. Mental Component Score (MCS): Provides greater emphasis on questions about role-emotional, vitality/mental health and social functioning. PCS and MCS summary scores are standardized using a z-score transformation and normed to a U.S. population (based on a 1990 norm) of a score of 50 and a standard deviation of 10. Higher MCS and PCS scores reflect better overall physical and mental health, respectively.

    Measured: 90 days postoperatively

  6. Hip Range of Motion

    Median hip range of motion (extension, in degrees) at 4 weeks postoperatively

    Measured: 4 weeks postoperative

  7. Knee Extension

    Median knee extension (degrees) at 4 weeks postoperatively

    Measured: 4 weeks postoperative
