Study summary

The purpose of this study is to evaluate how well subjects heal after surgery who receive standard dressings or incisional negative pressure wound therapy for non-traumatic amputation sites.

Read the detailed description

Incisional negative pressure wound therapy is an approved device used for wound healing of closed surgical incisions. This research is being done because incisional negative pressure wound therapy is a new application of negative pressure wound therapy that is applied over a closed incision area instead of an open wound. Negative pressure wound therapy is commonly used to help heal open wounds. It involves the use of a piece of foam, an adhesive drape, and a battery-powered device that places negative pressure on the wound. Currently, there are no trials utilizing incisional negative pressure wound therapy of closed wounds after below knee amputations (BKA), transmetatarsal amputations (TMA), Knee Disarticulations (KD), and Above Knee Amputations (AKA). This is a pilot study that compares incisional negative pressure wound therapy and standard dressings in patients.

Inclusion criteria

  1. Must be at least 18 years or older to participate.
  2. Requires closure of a nontrauamtic Transmetatarsal Amputation (TMA), Below Knee Amputation (BKA), Knee Disarticulation (KD), or Above Knee Amputation (AKA).

  4. Able to comply with clinical trial procedures and schedule.

Exclusion criteria

Study arms

  • Other
    Group A: Standard Dry Dressing

    The standard dry dressing is comprised of nonadherent dressing, dry gauze, cotton undercast padding, compression, and immobilization.

    Other: Standard Dry Dressing

  • Active comparator
    Group B: Foam, Drape, and PrevenaTM

    This arm is comprised of foam, drape, the PrevenaTM Device, compression, and immobilization.

    Device: PrevenaTM Device

Interventions

  • DevicePrevenaTM Device

    The PrevenaTM Incision Management System covers and protects the incision from external contamination, while negative pressure removes fluid and infectious material from the surgical incision.

  • OtherStandard Dry Dressing

    These are customary dry dressings.

What researchers measure

Primary outcomes

  1. Proportion of postoperative incision complications between the 2 arms

    The proportion of issues that arise between the two groups after closure surgery.

    Time frame: 95 days

Secondary outcomes

  1. Length of hospital stay

    The amount of time the patients must stay after closure surgery.

    Time frame: 5 days

  2. Number of surgically related wound readmissions

    The number of times patients are readmitted to the hospital for their surgical wound post-discharge.

    Time frame: 95 days

  3. Medical Outcomes Study 12 Short Form Health Survey (SF-12)

    Change in quality of life from the start of the study to the end.

    Time frame: 95 days

  4. Percentage of closed incisions remained closed at 1, 2 and 3 months post-hospital discharge

    The percentage of closed surgical wounds that remain closed after 1, 2 and 3 months after their closure surgery.

    Time frame: At 1, 2, and 3 months post-hospital discharge

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Nov 2017 (actual). Primary completion is estimated for Sep 2020, 34 months after the start.

Of 99 non-industry interventional studies with no phase under Surgical Wound, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 53. This study's planned 34 months is above that.

Counting every sponsor, half of 126 studies reached it within 18 months; a quarter within 9 and three quarters within 42.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 25, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
