## Abstract

Anterior cruciate ligament reconstruction can be painful, and both the femoral triangle block and local infiltration analgesia have been shown to provide effective analgesia after this surgery. A relatively new block, the iPACK (infiltration between the popliteal artery and the capsule of the knee), has been reported to provide posterior knee analgesia. In this triple-blinded, randomized controlled trial of 60 patients, the combination of femoral triangle block and iPACK block reduced opioid consumption for 24 hours postoperatively compared with local infiltration analgesia.1 However, other pain and functional outcomes were the same in both groups.
