Prospective Evaluation of Exparel Adductor Canal Field Block for Pain Control After Anterior Cruciate Ligament Reconstruction

Patients enrolled in the study will have a 50/50 chance of receiving either standard bupivacaine (a localized pain killer) or Exparel (our study version of this pain killer) as a block given in the interior thigh (to provide pain relief down the leg). In addition to receiving one of these two medications, all participants will receive a postoperative pain diary in which they will record their daily pill use, and pain scores until their visit at approximately 2 weeks. The diaries will allow us to gather information on day-to-day changes in pill use patterns and pain scores. The pain scales that we will utilize include the numeric pain rating scale (NRS) which is a common measure used in the literature that ranges from 0-10, and an intervention-based pain scale based on medication usage, needs, and how well their current medication regimen is treating their pain.
