What this Trial Is About

The goal of this randomized controlled trial is to compare opioid medication consumption after surgery for patients who have a total knee replacement. The main questions it aims to answer are: * How well does the study drug control pain in the days after surgery? * Does the study drug reduce the amount of opioid analgesic consumed after surgery? Participants in the study group will undergo a total knee replacement as planned with their surgeon. In addition, be given the study drug, Zynrelef (combination of bupivacaine and meloxicam). Researchers will compare the above to a control group who will have a total knee replace only according to usual standards to see if there are any differences in the amount of a type of pain medication (opioid analgesic) consumed in the days following surgery.
