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.

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.

Outcomes

Primary Outcomes

Postoperative Quality of Recovery (QoR-15 Score)

Postoperative quality of recovery will be assessed using the validated Quality of Recovery-15 (QoR-15) questionnaire. The total score ranges from 0 to 150, with higher scores indicating better recovery.

Time frame: 24 hours after surgery

Secondary Outcomes

Quality of Recovery (QoR-15) Score at 48 Hours

Quality of recovery will be assessed using the validated Quality of Recovery-15 (QoR-15) questionnaire (0-150, higher scores indicate better recovery).

Time frame: 48 hours after surgery

Postoperative Pain Intensity

Pain intensity will be assessed using an 11-point Numeric Rating Scale (NRS), where 0 indicates no pain and 10 indicates the worst imaginable pain.

Time frame: 2, 6, 12, 24, and 48 hours after surgery

Total Opioid Consumption

Total postoperative opioid consumption during the first 24 hours will be recorded and converted to intravenous morphine milligram equivalents (MME).

Time frame: 0-24 hours after surgery

Time to First Rescue Analgesia

Time from the end of surgery to the first rescue opioid administration will be recorded

Time frame: Within the first 24 hours after surgery

Time to First Mobilization

Time from the end of surgery to first assisted ambulation will be recorded

Time frame: Within the first 48 hours after surgery

Quadriceps Motor Strength

Quadriceps muscle strength will be evaluated using the Medical Research Council (MRC) scale ranging from 0 (no contraction) to 5 (normal muscle strength).
