Summary
This is a prospective, randomized, single blinded trial involving human subjects. The goal of this study is to determine an optimal location (proximal or distal) for the nerve block and whether it will make a difference in how much opioid the patient will receive during and after surgery. Ultrasound will identify the adductor canal and the proximal end of the adductor canal/apex of the femoral triangle to determine the location of the blocks.
Their will be two randomized groups: 1. ACB within true AC with bupivacaine 0.5% 20cc2. ACB proximal to true AC with bupivacaine 0.5% 20cc
