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.

Interventions

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.

OTHERControl

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.
