Effects of Perioperative Dronabinol Use in Total Knee Arthroplasty

Detailed Summary

The goal of this double-blinded randomized controlled trial is to compare whether the addition of Dronabinol compared to a placebo will affect opioid intake in patients undergoing a total knee arthroplasty. The main question it aims to answer are: 1. Does perioperative dronabinol use (starting in the immediate preoperative period (enrollment before 1 PM), with BID dosing concluding the evening of POD2) affect postoperative opioid consumption 24-48 hours following total knee arthroplasty? 2. Is there an effect of perioperative dronabinol use in the total knee arthroplasty patient on POD2 pain scores with ambulation? 3. Will hospital length of stay following total knee arthroplasty be affected in patients who use perioperative dronabinol as compared to control? 4. Does the use of perioperative dronabinol affect time to reach physical therapy discharge goals in postoperative total knee arthroplasty patients? 5. Is there a change in number of postoperative oxygen desaturation events in patients following total knee arthroplasty based on perioperative dronabinol use? Participants will: * Be randomized to take the dronabinol or placebo medication in 5 dosage * Answer survey questions in regard to pain, postop nausea/vomiting, cognitive/adverse event, and outcome quality and support of decision making. * Be connected to a Masimo to record oxygen saturation and an Actigraph to record sleep quality. Researchers will compare two groups: 1) intervention group and 2) control group to see if dronabinol affects postoperative opioid consumption 24-48 hours following their total knee arthroplasty surgery.
