Combined Adductor Canal and Infiltration in the Space between Popliteal Artery and Posterior Capsule of the Knee Blocks (IPACK) Versus Combined Genicular Nerve Block and Infiltration in the Space between Popliteal Artery and Posterior Capsule of the Knee Block (IPACK) in Total Knee Arthroplasty.

Optimal postoperative knee analgesia is important for not only patient comfort and satisfaction, but also for accelerating mobilization, functional recovery, and hospital discharge. Multimodal analgesia and motor-protective blocks are increasingly used to facilitate early ambulation and provide superior performance .The comparison of combined ACB and IPACK blocks versus combined GNB and IPACK blocks as analgesia for TKA is currently lacking in the anaesthesia literatures, thus this study compares the combination of ACB with IPACK blocks versus the combination of GNB with IPACK blocks regarding providing superior analgesia and limiting motor weakness. Also improving postoperative pain score, ambulation, and oral morphine equivalents
