This study aims to evaluate the effectiveness of a posterior hip capsule block performed in addition to a PENG (Pericapsular Nerve Group) block for patients undergoing hip arthroplasty. The primary objective is to assess whether this combined approach provides enhanced perioperative analgesia compared to the standard analgesic protocol or the PENG block alone. Secondary outcomes will focus on opioid consumption, functional recovery, and any potential complications. By targeting both the anterior and posterior innervation pathways around the hip joint, this combined technique could improve patient comfort, decrease opioid requirements, and potentially expedite rehabilitation after hip arthroplasty.
