The study investigated the benefit of adding dexamethasone to levobupivacaine in ultrasound-guided adductor canal block after anterior cruciate ligament reconstruction using bone, patellar tendon, and bone graft. During the first 24 hours after surgery, there was no difference between the groups in the percentage of patients experiencing pain (73.75% vs. 85%; χ² = 2.4433; p = 0.118) or in the severity of pain during activity (1.74 ± 0.97 vs. 1.59). There was no significant difference in opioid use during the first 48 hours. Three patients in the no-dexamethasone group reported rebound pain (χ² = 0.2564; p = 0.61). Blood glucose levels were significantly higher in the dexamethasone group (χ² = 4.329; p = 0.037).[6]
