Knee block mystery: does numbing agent reach the sciatic nerve?

NCT ID NCT07301476

First seen Jan 04, 2026 · Last updated Jun 11, 2026 · Updated 29 times

Summary

This study looks at why a numbing injection in the thigh (adductor canal block) works so well for knee surgery pain. Researchers think the medicine may spread to the sciatic nerve, but they want to measure how often this happens. About 70 adults having knee surgery will be tested for numbness and muscle strength one and four hours after the block. The goal is to better understand the block's pain-relieving effects, not to test a new treatment.
