Continuous Versus Single Injection Adductor Canal Blocks for Outpatient Total Knee Arthroplasty

Phase 4 Recruiting 40 enrolled University of California, San Diego

RandomizedParallel-groupOpen-labelTreatment

Summary

This is a single-center pilot study to determine if an adductor canal continuous nerve block is superior to single injection nerve block following total knee arthroplasty. Investigators will randomize participants to either continuous nerve block or single injection nerve block for the adductor canal preoperatively. They will assess differences in pain (measured in numeric rating scale), opioid consumption, and physical therapy milestones from postoperative day 0 to 7.
