About this study
Official title: Air Barrier System for the Reduction of Airborne Particulate and Colony Forming Units (CFU) During Total Knee Arthroplasty
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Air Barrier SystemDevice
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.
ControlOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Control | Sham comparator | 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. Receives: Other: Control |
| Air Barrier System | Experimental | 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. Receives: Device: Air Barrier System |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Four months
