NCT ID NCT04828083
First seen Mar 25, 2026 · Last updated May 22, 2026 · Updated 7 times
Summary
This study tested whether giving lidocaine through an IV works as well as a numbing shot near the knee (nerve block) for pain after knee replacement. 120 adults having knee surgery were randomly assigned to one of the two methods. The main goal was to see how much opioid pain medicine they needed after surgery. The study also looked at pain scores and how well patients felt they recovered.
