What this Trial Is About
Adductor canal blocks (ACB) have been recommended in total knee arthroplasty (TKA) to provide better control of post-operative pain, facilitate early ambulation, and reduce length of stay in the hospital. ACB is typically done before surgery by an anesthesiologist, which may increase time per case, cost, and requires the specialized skills of an anesthesiologist trained in regional anesthesia. Recent studies have suggested that surgeons can safely and reliably administer the adductor canal blocks (sACB) during surgery. However, there is currently very limited data on the clinical efficacy of such sACBs, and no studies assessing this technique in the context TKA that are discharged the same day. As such, this randomized control trial (RCT) is being done to compare sACBs to conventional anesthesiologist-performed adductor canal blocks (aACB).
