This study aimed to examine the impact of preoperative lumbar plexus blockade on perioperative analgesia and opioid consumption following hip arthroscopy. The records of patients (n = 236) who underwent hip arthroscopy between July 27, 2004 and November 15, 2009 were reviewed (118 patients with preoperative lumbar plexus block and 118 procedure matched patients without a preoperative block). Baseline patient characteristics were similar between groups. Immediate post-anaesthesia care unit (PACU) pain scores, peak PACU pain scores, perioperative opioid administration, and PACU antiemetic administration favoured preoperative block placement. Postoperative modified Harris Hip scores and postoperative day one pain scores were similar between groups. Total hospital time following the surgical procedure was longer in the block group. While preoperative lumbar plexus blockade may be helpful for analgesia following hip arthroscopy, more research needs to be done to determine the ideal analgesic regimen for these patients.
