Brief Summary
This study will test the use of active noise cancelling headphones with music or a movie during knee replacement surgery. Feedback from the surgical team and from patients regarding the headset system will be gathered to see if using it can reduce the amount of sedation needed during knee replacement procedures that use localized anesthesia.

Outcome Measures
Primary Outcomes (3)
Mean Richmond Agitation-Sedation Scale(RASS) Score
Richmond Agitation-Sedation Scale (RASS) measures the amount of sedation necessary for a patient at different levels of discomfort or agitation during local anesthesia surgeries.
30 minutes intraoperatively
Protocol Completion
This will measure the volume of patients that were unable to complete their procedure using spinal anesthesia and due to discomfort or agitation required deep sedation to continue to surgery.
Intraoperatively
Mean Propofol Infusion Rate
Mean rate of propofol infusion necessary to achieve sedation targets during the procedure. Unit: mcg/kg/min
Intraoperatively
Secondary Outcomes (3)
Patient Satisfaction
Within 48 hours post-operatively
Surgeon Satisfaction
Within 48 hours post-operatively
Anesthetist Satisfaction
Within 48 hours post-operatively
Study Arms (2)
No active noise cancelling headset
NO INTERVENTIONThis arm will serve as the control group for this randomized trial. Patients in this arm will receive normal standard of care anesthesia during their total knee arthroplasty.
Active Noise Cancelling Headset
EXPERIMENTALThis arm will provide patients with an active noise cancelling headset system that they may use to select music or a movie for audiovisual distraction during the surgery.
Interventions
The ANC Headset will allow patients to select music or a movie for audiovisual distraction during their surgery. This can be used when patients are not receiving general anesthesia (full sedation) for their surgery.
