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.

RECRUITINGMean 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.
Time frame: 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.
Time frame: Intraoperatively
Mean Propofol Infusion Rate
Mean rate of propofol infusion necessary to achieve sedation targets during the procedure. Unit: mcg/kg/min
Time frame: Intraoperatively
Patient Satisfaction
Patients will complete a satisfaction questionnaire post-operatively to determine their level of comfort with the sedation protocol they received during surgery.
Time frame: Within 48 hours post-operatively
Surgeon Satisfaction
Surgeons will be asked if they experienced interruptions or difficulty completing the procedure due to the sedation protocol administered to the patient.
Time frame: Within 48 hours post-operatively
Anesthetist Satisfaction
Anesthesia staff will receive a questionnaire regarding satisfaction with efficacy of the sedation protocol administered during the surgery.
Time frame: Within 48 hours post-operatively
