Resumen del estudio

Ninety-six patients undergoing anterior cruciate ligament reconstruction (ACLR) with a bone–patellar tendon–bone (BTB) autograft were randomized to receive either an adductor canal block alone (n=47) or a combination of adductor canal and IPACK block (n=49). The primary outcome was opioid consumption at 24 hours postoperatively. Secondary outcomes included opioid use at days 2, 3, and 7; visual analog scale (VAS) pain scores; patient satisfaction with pain control; and postanesthesia care unit (PACU) time. Outcomes were assessed at postoperative days (POD) 1, 2, 3, and 7. Overall, the results of the study revealed significantly lower opioid use and pain scores on POD 1–3 in the combined block group, along with higher satisfaction on POD 1. No differences were observed by POD 7. These findings suggest that the addition of an IPACK block provides improved early postoperative pain control and reduces opioid consumption after ACLR with a BTB autograft.
