Genicular and Anterior Femoral Cutaneous Nerve Blocks for Total Knee Arthroplasty
Summary
The goal of this randomized controlled trial is to examine if there is a relationship between the addition of the genicular nerve block and anterior femoral cutaneous nerve block in providing analgesia and the use of oral and intravenous medication in patients undergoing a total knee arthroplasty. The main questions it aims to answer are: 1. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' total opioid consumption in the first 24 hours after total knee arthroplasty (TKA) surgery? 2. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' worst numeric rating scale (NRS) pain score in the post-anesthesia care unit (PACU)? 3. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care result in earlier discharge from the post-anesthesia care unit (PACU)? 4. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' total opioid consumption in the first 7 days after total knee arthroplasty (TKA) surgery? 5. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' numerical rating scale (NRS) pain (both at rest and during movement) in the first 24 and 48 hours after surgery? Participants will be randomly assigned to receive the genicular nerve block and anterior femoral cutaneous nerve block in addition to standard of care (intervention group), or not receive the nerve blocks (control group). Comparing the intervention group to the control group, the researcher's primary outcomes are numerical pain in the post-anesthesia care unit and cumulative opioid consumption during the first 24 hours.
