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

Eligibility
Inclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale (VAS) Pain Score | Day 8 | A patient is asked to indicate his/her perceived scar severity along a 100 mm horizontal line, and this rating is then measured from the left edge (=VAS score). The total score range is 0 (worst possible scar) to 100 (best possible scar); the higher the score, the better the scarring. |
| Wound Evaluation Scale (WES) | Day 8 | WES is a 6-item scale. Items 1-5 are scored 0 (yes) or 1 (no), and item 6 is scored 0 (poor) or 1 (acceptable). The total score range is 0-6; the higher the score, the more optimal the wound healing. |
