First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study will compare two types of nerve blocks for pain relief after knee arthroscopy. 72 adults scheduled for knee surgery will receive either an adductor canal block or a genicular nerve block, both combined with an IPACK block. The goal is to see which method delays the need for pain medication and reduces pain scores.
