PENG nerve block with or without pulsed radiofrequency for chronic hip osteoarthritis pain
Evaluation of the Clinical Effectiveness of Pericapsular Nerve Group (PENG) Block and Pulsed Radiofrequency Applications in Chronic Hip Pain
The study will try adding pulsed radiofrequency to a PENG nerve block to see if it reduces pain for longer in people with chronic hip osteoarthritis who still have significant pain despite conservative treatment.

What this trial studies
This is a prospective observational comparison of two interventional approaches for chronic hip osteoarthritis pain: ultrasound-guided pericapsular nerve group (PENG) block alone versus PENG block combined with pulsed radiofrequency (PRF). The primary outcome is change in pain intensity measured by the Visual Analog Scale, and secondary outcomes include hip function assessed with validated functional scales. Eligible patients are adults with chronic hip pain lasting at least three months, baseline VAS ≥4, and inadequate response to conservative care. Procedures are performed at a single center with follow-up to determine whether adding PRF yields longer-lasting analgesia and functional benefit.
Who should consider this trial
Good fit: Adults with chronic hip pain for at least three months due to clinical or radiographic hip osteoarthritis, baseline VAS score of 4 or higher, and inadequate response to conservative treatments are ideal candidates.
Not a fit: Patients with hip pain from malignancy, prior hip arthroplasty, active local or systemic infection, uncorrectable coagulopathy or inability to stop anticoagulants, severe neurological deficit, or who are pregnant or breastfeeding are unlikely to benefit or are excluded.
Why it matters
Potential benefit: If successful, adding PRF to the PENG block could provide longer-lasting pain relief and better hip function, reducing the need for repeat procedures and improving daily activities.
How similar studies have performed: Previous small studies show PENG blocks provide short-term pain relief and PRF has produced promising results in other joint pain settings, but combining PENG with PRF has limited published data and remains relatively untested.
