简要总结
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.
详细描述
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.

研究组 & 干预措施
Air Barrier System
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.
干预措施: Air Barrier System (Device)
Control
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.
干预措施: Control (Other)
结局指标
主要结局
Compare the number of colony-forming units captured at incision sites
时间窗: Four months
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.
