NCT ID NCT07040709

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested two types of nerve blocks—adductor canal block and suprainguinal fascia iliaca block—to see which controls pain better after total knee replacement. 86 adults having knee replacement under spinal anesthesia were randomly assigned to one block. Researchers measured pain scores and opioid use in the first 24 hours after surgery.
