PENG Block & PENG PRF

Evaluation of the Clinical Effectiveness of Pericapsular Nerve Group (PENG) Block and Pulsed Radiofrequency Applications in Chronic Hip Pain

Sponsor

Ankara City Hospital Bilkent

Enrollment

84 participants

Start Date

Feb 1, 2026

Study Type

OBSERVATIONAL

Conditions

Osteoarthritis (OA) of the hip

Summary

The primary aim of this study is to prospectively compare the effects of the pericapsular nerve group (PENG) block alone and the combination of PENG block with pulsed radiofrequency (PRF) on pain intensity in patients with chronic hip pain. As a secondary aim, the effects of both treatment modalities on hip function are intended to be evaluated using valid and reliable functional assessment scales. Through this study, it is aimed to demonstrate the clinical contribution of adding PRF to the PENG block and to identify a more effective and longer-lasting approach for the interventional treatment of chronic hip pain.

Interventions

PROCEDUREPENG Block Pulsed radiofrequency

This intervention consists of a stepwise, two-stage treatment protocol routinely applied in our clinical practice for the management of chronic hip pain. In the first stage, all patients undergo an ultrasound-guided pericapsular nerve group (PENG) block as a diagnostic and therapeutic procedure. Pain intensity is assessed using the Visual Analog Scale (VAS) following the diagnostic block. Only patients who demonstrate a clinically meaningful response, defined as a reduction of 50% or greater in VAS scores, proceed to the second stage of the intervention. In the second stage, pulsed radiofrequency (PRF) treatment is applied to the same target region in addition to the PENG block, aiming to achieve longer-lasting analgesia through neuromodulation without tissue destruction.
