The goal of this clinical trial is to determine whether adding a posterior pericapsular deep-gluteal (PPD) block to pericapsular nerve group (PENG) and lateral femoral cutaneous nerve (LFCN) blocks improves pain control after total hip arthroplasty.
The main questions it aims to answer are:
Researchers will compare patients receiving PENG and LFCN blocks with patients receiving PENG and LFCN blocks plus a posterior pericapsular deep-gluteal block to determine whether blocking the posterior region of the hip provides additional pain relief.
Participants will:
Total hip arthroplasty is commonly associated with moderate to severe postoperative pain. Providing effective analgesia can be challenging because of the complex innervation of the hip joint, and no single nerve block or combination of blocks has been demonstrated to be superior for all types of hip surgery.
The pericapsular nerve group (PENG) block and lateral femoral cutaneous nerve (LFCN) block are regional anesthesia techniques used to reduce pain after hip surgery. However, these blocks mainly target the anterior and lateral regions of the hip and may not adequately cover pain arising from the posterior region.
The posterior pericapsular (deep-gluteal) block (PPD) is a recently described regional anesthesia technique designed to target the nerves supplying the posterior region of the hip while preserving motor function. Evidence regarding the additional analgesic benefit of this block in patients undergoing total hip arthroplasty remains limited.
This randomized controlled study will compare patients receiving PENG and LFCN blocks with patients receiving PENG and LFCN blocks combined with PPD block. The primary aim is to determine whether adding the posterior pericapsular (deep-gluteal) block reduces clinically significant pain during movement in the early postoperative period. The study will also evaluate postoperative pain, opioid consumption, and quality of functional recovery.
The investigators hypothesize that adding the posterior pericapsular (deep-gluteal) block to PENG and LFCN blocks will provide better early postoperative analgesia than PENG and LFCN blocks alone.

PENG block: 20 ml %0.25 Bupivacaine LFCN block: 5 ml %0.50 Bupivacaine PPD block: 15 ml %0.25 Bupivacaine
Procedure: PENG (Pericapsular nerve group) block · Procedure: LFCN (Lateral femoral cutaneous nerve) block · Procedure: PPD (Posterior pericapsular deep gluteal) block
An ultrasound-guided pericapsular nerve group (PENG) block will be performed in the preoperative period, approximately 30 minutes before surgery.
An ultrasound-guided lateral femoral cutaneous nerve (LFCN) block will be performed in the preoperative period, approximately 30 minutes before surgery.
An ultrasound-guided posterior pericapsular deep-gluteal block will be performed in the preoperative period, approximately 30 minutes before surgery.
6-hour dynamic pain intensity
Dynamic pain will be assessed using the Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain).
Time frame: 6 hours postoperatively
Dynamic pain intensity
Dynamic pain will be assessed using the Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain).
Time frame: 4, 8, 12, and 24 hours postoperatively
Pain intensity at rest
Resting pain will be assessed using the Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain).
Time frame: 4, 6, 8, 12, and 24 hours postoperatively
Cumulative morphine consumption
The cumulative amount of morphine consumed during the first 24 hours postoperatively will be recorded in milligrams (mg).
Time frame: Up to 24 hours postoperatively
Time to first rescue analgesic
The time from the end of surgery to the first pain score ≥ 4 at rest or during movement, or to the first patient request for analgesia, will be recorded in hours.
Time frame: Up to 24 hours postoperatively
Quality of Recovery (QoR)-15 score
Quality of postoperative recovery will be assessed using the 15-item Quality of Recovery (QoR-15) questionnaire. The total score ranges from 0 to 150, with higher scores indicating better quality of recovery.
Time frame: Preoperatively and postoperative day 1
Patient satisfaction score
Patient satisfaction with postoperative pain management will be assessed using a numerical rating scale ranging from 0 (completely dissatisfied) to 10 (completely satisfied), with higher scores indicating greater satisfaction.
Time frame: Postoperative day 1
Sleep quality score
Sleep quality during the first postoperative night will be assessed using a 5-point numerical rating scale ranging from 1 (very poor) to 5 (very good), with higher scores indicating better sleep quality.
Time frame: Postoperative day 1
