    Arm 1

    Arm 2

    Arm Type

    Sham Comparator

    Experimental

    Arm Label

    Control

    Air Barrier System

    Arm Description

    In the control arm, the ABS device will be placed as usual on the patient, but the airflow will NOT be activated. Only the technician in the room will be aware whether the device is turned on or not.

    In the experimental (intervention) arm, the ABS device will be placed as usual on the patient, and the airflow will be activated. Only the technician in the room will be aware whether the device is turned on or not.

    Outcomes

    Primary Outcome Measures

    Compare the number of colony-forming units captured at incision sites
    A length of tubing will be placed at the incision and will draw air onto agar plates that are changed every ten minutes in both the control and ABS arms.

    5. Study Description

    Brief Summary
    This objective of this study is to determine whether the Air Barrier System device reduces airborne colony-forming units (e.g., bacteria) present at a surgery site during total knee arthroplasty surgeries.
    Detailed Description
    The Air Barrier System (ABS) is a device that uses localized clean air flow to shield a surgery site from ambient airborne contamination. This study examines the hypothesis that the ABS can reduce the presence of airborne CFU at the surgery site during total knee arthroplasty surgery.

    Intervention Type
    Device
    Intervention Name(s)
    Air Barrier System
    Intervention Description
    The Air Barrier System is a device that uses localized clean air flow to shield a surgery site from ambient airborne microorganisms that are shed into the air from people present in the operating room.
    Intervention Type
    Other
    Intervention Name(s)
    Control
    Intervention Description
    The Air Barrier System will be deployed onto the surgical field, but the airflow will not be activated, so this is a sham control comparator.
    Primary Outcome Measure Information:
    Title
    Compare the number of colony-forming units captured at incision sites
    Description
    A length of tubing will be placed at the incision and will draw air onto agar plates that are changed every ten minutes in both the control and ABS arms.
    Time Frame
    Four months
