Background: Adductor canal block (ACB) has recently been considered as a promising method for providing analgesia after knee surgeries with sensory blockade. ACB blocks the sensory innervation of the knee via the saphenous nerve [1]. ACB preserves quadriceps muscle strength better than Femoral Nerve Block, minimizing weakness during knee extension and thus functional recovery is improved within the first 24 hrs post‑ operative period and the risk of developing Deep Vein Thrombosis is reduced [1]. Addition of Dexamethasone to local anaesthetics improves the quality and duration of peripheral nerve block [2] . We evaluated the effect of adding dexamethasone to levobupivacaine on the duration of postoperative analgesia in patients undergoing knee surgery using ultrasound-guided adductor canal block.
