Efficacy of Adductor Canal Blocks in Total Knee Arthroplasty

Total knee arthroplasty (TKA) is associated with significant postoperative pain. The population receiving TKA is generally elderly and often have multiple comorbidities that can present a challenge to postoperative management. Safe and effective multimodal pain management has led to improved outcomes while minimizing complications and side effects. The objective of this study was to investigate the efficacy of adductor canal blocks (ACB) in patients receiving TKA within a regional Queensland population. We performed a retrospective comparative cohort analysis of 458 patients who received TKA at a regional private hospital between January 2016 and December 2018. Inclusion criteria included body mass index (BMI)
