Antimicrobial Barrier Dressing Versus Closed-incision Negative Pressure Therapy in the Obese Primary Total Joint Arthroplasty

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions


Active Comparator: Antimicrobial Barrier Dressing

postoperative wound dressing with either anti-microbial dressing placed in the operating room from surgery to postoperative day 7

Active Comparator: Closed-incision Negative Pressure Therapy

portable NPWT device placed in the operating room from surgery to postoperative day 7


Combination Product: - Antimicrobial Barrier Dressing

Ionic Silver is a soft, nonwoven pad or ribbon that features the gelling benefits of Hydrofiber technology plus antimicrobial ionic silver.

Device: - Negative Pressure Wound Therapy (NPWT)

PICO provides suction known as negative Pressure wound Therapy (NPWT) which draws out excess fluid from a wound and protects the injured area from getting dirty to ultimately help promote healing. PICO consists of an nPwT pump connected to an absorbent gentle adhesive dressing
