Adductor Canal Block (ACB) + iPACK Block
"Adductor Canal Block (ACB) in the immediate preoperative period under a high-frequency ultrasound guidance in which the adductor canal is identified beneath the sartorius muscle and 20 ml of bupivacaine 0.25% will be injected in the canal using a 22-gaugusing a 22-gauge 100-mm short-bevelled regional block needle.~IPACK Block which the patient will be placed in a supine position and knee will be placed in position of 90° flexion. A low-frequency ultrasound probe will be positioned in the popliteal crease, and a spinal needle will be inserted from the medial aspect of the knee from anteromedial to posterolateral direction in a plane between the popliteal artery and the femur. The tip of the needle will be placed 1-2 cm beyond the lateral edge of the artery, and 15 ml of bupivacaine 0.25% will be injected after negative aspiration."
