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.
