Summary
Arthroscopic knee injuries, such as the anterior cruciate ligament (ACL) injury, are common and often result in postoperative pain. Regional anesthetic techniques, such as femoral nerve block (FNB) and adductor canal block (ACB), can help alleviate pain and reduce opioid consumption. ACB, which blocks the saphenous nerve and obturator nerve branches, is preferred over FNB due to its potential to decrease mobility and increase falls risk. Dexamethasone, a potent glucocorticoid, is used as an adjuvant for ACB, but its perineural administration may carry neurotoxicity risks. Some pain physicians prefer intravenous administration to prolong the action of local anesthetics used in peripheral nerve blocks.
