Lee S, et al. - In this study, researchers tested their hypothesis that adductor canal blocks (ACB) single injection plus intravenous (IV) dexamethasone (Dex) shows non-inferiority to catheter for analgesia after total knee arthroplasty (TKA), while ACB single injection does not. Findings revealed that single injection ACB, with and without IV dexamethasone was non-inferior to ACB catheters in 24h opioid consumption and thus could be considered as attractive options for early discharge fast track TKA.
