Recovery after Hip Arthroplasty with Quadro-Iliac Plane Block: A Randomised Trial

İngilizce (OpenAlex)

OBJECTIVE: To evaluate the effectiveness of the quadro-iliac plane block (QIPB) in enhancing postoperative recovery after total hip arthroplasty (THA), using the quality of recovery-15 (QoR-15) score. STUDY DESIGN: Randomised, controlled, multicentre study. Place and Duration of the Study: Konya City Hospital and Harran University, Faculty of Medicine, Turkiye, between March and April 2025. METHODOLOGY: Patients were randomised to receive either the QIPB (Group Q) or multimodal analgesia alone (Group C), with a total of 64 participants enrolled. The primary measure was the QoR-15 score, evaluated 24 hours postoperatively. The total QoR-15 scores were normally distributed and compared between the groups using an independent samples t-test. Secondary measures comprised postoperative pain intensity, the quantity of rescue analgesics administered, time to initial analgesic intervention, overall patient satisfaction, and the incidence of nausea, vomiting, and antiemetic administration. RESULTS: Group Q demonstrated significantly higher QoR-15 scores compared to Group C (Group Q: 127 ± 4; Group C: 89 ± 7; p <0.001). Furthermore, Group Q achieved superior scores across all subdomains, including postoperative pain, physical comfort, physical independence, psychological support, and emotional state (p <0.001). CONCLUSION: The QIPB is a novel and effective regional analgesic technique that offers significant postoperative pain relief, enhances patient comfort and satisfaction, and contributes positively to the quality of recovery after THA.
