A Pilot Randomized Controlled Trial of Suzetrigine as an Adjunct to Multimodal Analgesia Following Total Knee Arthroplasty

This proposal seeks to determine if the addition of Suzetrigine, a novel non-opioid pain medication, to a standardized multimodal pain management pathway significantly reduces total postoperative opioid consumption (measured in Morphine Milligram Equivalents [MME]) and improves patient-reported pain scores during the first 14 days following primary total knee arthroplasty (TKA). Prior to conducting a definitive randomized control trial (RCT), we propose a pilot study to inform the trial's design and feasibility.

Objective: To inform the design and feasibility of a definitive RCT comparing postoperative pain control with and without Suzetrigine after TKA. To achieve this objective, we will conduct a pilot trial and address the following aims:

1) to determine if participant enrollment is feasible, 2) to assess compliance with treatment protocol and key aspects of the protocol, and 3) to refine data collection methods.
