About this trial
The goal of this interventional clinical trial is to assess opioid consumption 24-48 hrs post anesthesia block among patients undergoing total knee arthroplasty. The main question it aims to answer is:
1\. Is there a difference in opioid consumption 24-48 hours post block administration among patients that receive an adductor canal catheter (ACC) versus adductor canal block (ACB)?
Participants will be:
* Randomized to receive an adductor canal catheter (ACC) or a sham adductor canal catheter. * Asked to use the Diagnotes application to communicate with the pain doctor while the catheter is in place. * Follow up for up to 6 months post-operation. Researchers will compare the interventional group (ACC) to the control group (sham ACC + ACB) to see if there is difference in opioid consumption and chronic pain at 6 months post-operation.

Treatment groups
Trial outcomes
Primary outcomes
Opioid consumption at 24-48 hours
The cumulative opioid consumption 24-48 hours post block administration. Measured in morphine milligram equivalents per day. Although collected over a period of time, the total amount will be summed and the average will be reported.
Secondary outcomes
Opioid consumption at 72 hours, 96 hours, and 1 week
The cumulative opioid consumption 72hours, 96 hours, and 1 week post block administration. Measured in morphine milligram equivalents per day. Although collected over a period of time, the total amount will be summed and the average will be reported.
Numerical Pain Rating Score
Patients are asked to give a number between 0 and 10 that best fits their pain intensity. The scale is 0 = 'no pain at all' whereas 10 = 'the worst pain ever possible'. Measured at multiple time points: DOS, post-operative day (POD) 1, POD 2, POD 3, POD 4, POD 7, \& POD 60
Physical Therapy Milestones
Collected from the physical therapy notes. This outcome will assess for time to ambulation (measured in distance traveled, stairs, time of ambulating \> 30 meters, and reaching discharge criteria).
Patient Satisfaction with Pain Control
Patients are asked to report on their satisfaction with pain control on a scale of 0 to 10, with 0 = extremely dissatisfied and 10 = extremely satisfied.
