Total knee arthroplasty (TKA) is accompanied by moderate to severe postoperative pain. Multimodal analgesia, such as femoral nerve block, periarticular infiltration analgesia (PIA), and patient-controlled intravenous analgesia, have been used for postoperative analgesia. Recently, randomized controlled trials have compared the efficacy of the adductor canal block (ACB) and the PIA in patients undergoing TKA. However, there is no definite answer as to the efficacy and safety of the ACB compared with the PIA.
