Adductor Canal Block In Anterior Cruciate Ligament (ACL) Repair

Not Applicable

Completed

• Conditions: Neuromuscular Block
• Interventions: Procedure: Adductor Canal Block; Procedure: Femoral Nerve Block

• Registration Number: NCT01791036
• Lead Sponsor: University Health Network, Toronto

Brief Summary

Adductor canal block will provide adequate analgesia to patients undergoing arthroscopic ACL reconstruction surgery, yet result in less motor blockade than a femoral block.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Pain Scores	12,24 and 48 hours	Visual Analog Pain scores at rest and with movement at admisssion and discharge from post-anesthesia care unit (PACU), AT DISCHARGE FROM same day surgery unit (SDC) and at 12, 24 and 48 hours
