Effects of Genicular Nerve Blocks in Combination With an Adductor Canal Block in Patients Undergoing Arthroscopic Knee Surgery: A Randomized Controlled Trial

Adding GNBs to an ACB did not demonstrate superiority in reducing postoperative pain scores. However, it effectively reduced perioperative opioid consumption at 12 to 48 hours postoperatively without increasing adverse effects such as nausea, vomiting, or motor blockade. These findings highlight the potential of GNBs as a valuable component of postoperative pain management strategies for arthroscopic knee surgery.
