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

What this Trial Is About

Researchers are evaluating the effects of the pericapsular nerve group (PENG) block alone compared to the combination of PENG block with pulsed radiofrequency (PRF) on pain intensity in patients with chronic hip pain, especially due to osteoarthritis. This study aims to find out if adding PRF to the PENG block can provide more effective and longer-lasting pain relief and improve hip function, using reliable functional assessment scales. Chronic hip pain often limits daily activities and may not respond well to standard treatments, making minimally invasive options important to explore. The treatment involves a two-stage approach. First, all participants receive an ultrasound-guided PENG block as a diagnostic and therapeutic procedure. If patients experience a significant reduction in pain (at least 50% less on the pain scale), they then receive pulsed radiofrequency treatment in addition to the PENG block. This method aims to modulate nerve signals to extend the pain relief without damaging tissues. Participants will be assessed at multiple points: before the procedure and then at 1 week, 1 month, 3 months, and 6 months afterward. Pain intensity is measured using the Visual Analog Scale (VAS), while hip function is evaluated with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Harris Hip Score (HHS). Researchers will also monitor analgesic use. The study is observational and will document outcomes of these treatments routinely used in clinical practice, with the total participation duration covering at least 6 months post-intervention.
