The effectiveness of an Exparel Block (Bupivacaine Liposomal Injectable Suspension) for post-operative pain control has been well studied with encouraging results. At the investigators' institution, Exparel has been approved as a safe and effective option for use in shoulder surgeries and have had encouraging results in adductor canal use for pain control in patients undergoing TKA. Exparel has been shown to have better pain control compared to previously used infiltration agents, including bupivacaine, while having a minor side effect profile. The purpose of this study is to explore the effectiveness of Exparel (liposomal bupivacaine) in Adductor Canal Blocks (ACB) for peri-operative pain control following a total knee arthroplasty (TKA) procedure. Specifically, the investigators look to see if Exparel ACB reduces opioid requirement use post-operatively, reduces pain scores post-operatively, provides earlier mobilization, and decreases length of hospital stay.
