Improvement in Wound Healing With Negative Pressure Wound Therapy for Postoperative Total Hip Arthroplasty

Improvement in Wound Healing With Negative Pressure Wound Therapy for Postoperative Total Hip Arthroplasty

For the target population of adult patients following primary total hip arthroplasty, the randomized clinical trial will be used to evaluate the efficacy of the use of a mobile negative pressure wound therapy(NPWT) device compared to a standard absorptive dressing in the immediate postoperative period. We will apply two dressing types and evaluate the postoperative wounds with a wound scoring system (ASEPSIS) that incorporates multiple variables of wound infection risk.

Inclusion Criteria:

- Adult patients undergoing primary total hip arthroplasty.

Exclusion Criteria:

• age less than 18 y/o
• Total hip arthroplasty for fracture
• Revision or conversion total hip arthroplasty
• inability to personally consent to participation due to cognitive impairment, intoxication or sedation
• multiple surgical procedures
• Patients taking immune modulating medication(prednisone, methotrexate, anakinra, etc.)
• skin hypersensitivity to acrylic adhesive or silver.
• Inability to care for dressing due to physical or mental incapacitation
