NCT ID NCT03033589
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial compares two types of nerve blocks—femoral nerve block and adductor canal block—for controlling pain after anterior cruciate ligament (ACL) reconstruction. Participants receive one of the two blocks before surgery, and researchers track their pain levels and painkiller use for three days after the operation. The goal is to find which block provides better pain relief while preserving muscle strength.
