Femoral Nerve Block Versus Adductor Canal Nerve Block for Peri-Operative Analgesia Following Anterior Cruciate Ligament (ACL) Reconstruction: Evaluation of Post-operative Pain and Strength

All patients over the age of 16 undergoing primary or revision anterior cruciate ligament reconstruction with the use of bone-patellar-bone autograft are eligible for the study. Patients will be randomized pre-operatively to receive either an adductor canal nerve block (single injection) or a femoral nerve block (single injection). Post-operatively, the primary outcome measures of pain level using visual analog scale as well as narcotic and non-narcotic analgesic requirements will be measured.
