Postoperative Analgesic Efficacy of ACB+iPACK vs FTB+Selective Tibial+Obturator Blocks in ACL Reconstruction

Evaluation of Postoperative Analgesic Efficacy in Anterior Cruciate Ligament Reconstruction: Ultrasound-Guided Adductor Canal Block Combined With iPACK Block Versus Femoral Triangle Block Combined With Selective Tibial and Obturator Nerve Blocks at Da Nang Hospital

This prospective, comparative study aims to evaluate the postoperative analgesic efficacy of ultrasound-guided Adductor Canal Block (ACB) combined with iPACK block versus Femoral Triangle Block (FTB) combined with selective tibial nerve block and obturator nerve block in patients undergoing arthroscopic anterior cruciate ligament (ACL) reconstruction. The primary objective is to determine which regional anesthesia regimen provides superior pain relief at rest and during movement. The secondary objectives include assessing morphine consumption, motor blockade using the Bromage score, patient satisfaction, and potential adverse effects of these anesthesia techniques.
