Comparison of Combination of Proximal ACB and iPACK With Large-Volume Distal ACB for Early Mobilization After TKR

The interventions are three different regional anesthesia techniques: Proximal Adductor Canal Block (ACB), iPACK (Interspace between the Popliteal Artery and the Capsule of the Posterior Knee), and Large-Volume Distal Adductor Canal Block (Large ACB distal). all three interventions were administered using ropivacaine 0.2%. However, there were differences in the volumes injected for each regional anesthesia technique. Proximal ACB: 15 mL of ropivacaine 0.2%. iPACK: 20 mL of ropivacaine 0.2%. Large ACB distal: 35 mL of ropivacaine 0.2%
