FEMORAL NERVE BLOCK VERSUS ADDUCTOR CANAL BLOCK FOR ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION IN PEDIATRIC AND ADOLESCENT PATIENTS

Adductor canal block (ACB) is an alternative method to femoral nerve block (FNB) for post-operative analgesia for anterior cruciate ligament reconstruction (ACLR) in pediatric and adolescent patients. Prior studies have suggested that FNB is associated with persistent strength deficits at 6 months after ACLR in this population. Proponents of the ACB consider that this method may result in a decreased incidence of quadriceps strength deficits during post-operative rehabilitation. The purpose of this study was to compare knee strength and function at 6 and 9 months after ACLR in pediatric and adolescent patients who received FNB versus ACB peri-operatively
