About this trial

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.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Ultrasound-guided Adductor Canal Block (ACB)

    Procedure/Surgery

    Ultrasound-guided administration of 10 mL levobupivacaine 0.2% into the adductor canal space to provide postoperative analgesia

  • Ultrasound-guided iPACK block

    Procedure/Surgery

    Ultrasound-guided administration of 15 mL levobupivacaine 0.2% into the space between the popliteal artery and the posterior capsule of the knee to provide posterior knee analgesia.

  • Ultrasound-guided Femoral Triangle Block (FTB)

    Procedure/Surgery

    Ultrasound-guided administration of 10 mL levobupivacaine 0.2% at the distal apex of the femoral triangle to provide anterior and medial knee analgesia

  • Ultrasound-guided Selective Tibial Nerve Block

    Procedure/Surgery

    Ultrasound-guided administration of 5 mL levobupivacaine 0.2% around the tibial nerve in the popliteal fossa

  • Ultrasound-guided Obturator Nerve Block

    Procedure/Surgery

    Ultrasound-guided administration of 10 mL levobupivacaine 0.2% targeting the anterior and posterior branches of the obturator nerve within the fascial planes between the adductor muscles.
