Postoperative Analgesia Produced by Adductor Canal (Distal Femoral Artery Compartment) Block Is Not Inferior to Femoral Nerve Block In Outpatient Arthroscopic Anterior Cruciate Ligament Repair
Postoperative Analgesia Produced by Adductor Canal (Distal Femoral Artery Compartment) Block Is Not Inferior to Femoral Nerve Block In Outpatient Arthroscopic Anterior Cruciate Ligament Repair
Adductor canal block will provide adequate analgesia to patients undergoing arthroscopic ACL reconstruction surgery, yet result in less motor blockade than a femoral block.
This study is designed to demonstrate that postoperative analgesia produced by the adductor canal block is not inferior to that produced by femoral nerve block in patients undergoing arthroscopic ACL reconstruction surgery. The study will also compare the degree of motor blockade of the adductor canal block to that of the femoral nerve block.
Inclusion Criteria:
American Society of Anesthesiologists(ASA)classification I-III, Patients 18 to 50 years of age, BMI 18 - 40. Patients scheduled for anterior cruciate ligament reconstruction surgery under general anesthesia and nerve blocks.
Exclusion Criteria:
Refusal or inability to provide informed consent. Any contraindication to regional anesthesia including coagulopathy or bleeding diathesis, allergy to local anesthetics, infection, nerve injury or malignancy at the site of the block.
History of alcohol/drug dependence. History of long term opioid intake or chronic pain disorder. History of preexisting neuropathy in the operative leg History of significant psychiatric conditions that may affect patient assessment.
Inability to understand the informed consent and demands of the study. Allergy to any of the components of the multimodal analgesic regimen.
