Continuous Vs Single Shot Adductor Canal Block After ACL Reconstruction - A Randomized Study

18-0811

The investigators will be randomizing patients to either receive an adductor canal block in the operating room postoperatively as single shot of 20-30cc bupivacaine or to have a catheter inserted into the adductor canal which will be attached up to a continuous infusion pump of bupivacaine that will have a set flow rate over the next couple days. The investigators' hypothesis is that patients will have better pain control, sleep, and decreased opioid consumption with the use of a continuous infusion pump
