Overview
This prospective randomized controlled trial evaluates the effect of ultrasound-guided unilateral Femoral Rami and Obturator Nerve Trunk (FRONT) block on postoperative quality of recovery in patients undergoing elective total hip arthroplasty.
Description
Total hip arthroplasty (THA) is associated with significant postoperative pain that may impair early recovery. The Femoral Rami and Obturator Nerve Trunk (FRONT) block is a regional anesthesia technique targeting sensory innervation of the anterior hip capsule and may improve postoperative recovery while preserving motor function. This prospective randomized controlled trial aims to evaluate whether the addition of ultrasound-guided unilateral FRONT block to standard multimodal analgesia improves postoperative quality of recovery in patients undergoing THA.
