Adductor canal block offers improved quadriceps strength, similar analgesia to FNB in ACLR
Anesthesiology. 2016 May;124(5):1053-64100 patients scheduled for arthroscopic anterior cruciate ligament reconstruction were randomized to receive regional anaesthesia pre-operatively through either an adductor canal block (ACB) or femoral nerve block (FNB). The purpose of this study was to determine if ACB demonstrated noninferior analgesic efficacy to FNB, and concurrent superior results to FNB with respect to post-block, preoperative quadriceps strength. The results of this study demonstrated nonsignificant differences between groups in analgesic consumption or pain scores postoperatively, while the ACB group demonstrated significantly higher maximal voluntary isometric contraction of the quadriceps in the post-block, preoperative phase compared to the FNB group.
