Dose adductor canal block combined with local infiltration analgesia has a synergistic effect than adductor canal block alone in total knee arthroplasty: a meta-analysis and systematic review

摘要

BackgroundBoth adductor canal block (ACB) and local infiltration analgesia (LIA) are effective procedures for postoperative pain control in total knee arthroplasty (TKA) without motor blockade. However, whether ACB combined with LIA has synergistic effect than ACB alone remains unknown. We hypothesized that ACB combined with LIA would have better postoperative pain control, less rescue opioid consumption and faster rehabilitation than ACB alone, without higher adverse event rate.
