Summary
The purpose of this project is to determine if a change in patient reported pain, nausea and vomiting after total knee arthroplasty can be observed with the substitution of a post operative adductor canal block for a preoperative adductor canal block in the current established peri-operative pain protocol and if these changes lead to a decrease in opioid consumption (in morphine equivalents).
