What this study is about

Researchers are testing whether using an adductor canal catheter (ACC) reduces opioid use 24-48 hours after surgery compared to a sham catheter in patients undergoing total knee arthroplasty. Participants will be randomized to receive either the ACC or a sham catheter and asked to communicate with their pain doctor through a mobile app while the catheter is in place. The trial will last up to 6 months post-operation, and researchers will compare opioid use and chronic pain between the two groups at that time.
