Pulsed radiofrequency to femoral and obturator nerve branches for hip pain
Official title: A Study on the Effectiveness of Pulsed Radiofrequency Treatment Applied to the Femoral and Obturator Nerve Articular Branches Under Ultrasound Guidance in Chronic Hip Osteoarthritis
Run by Diskapi Teaching and Research Hospital · NCT07190339 · Data updated 2026-11-12
This trial will try ultrasound-guided pulsed radiofrequency on the femoral and obturator nerve branches to reduce hip and groin pain and improve function in people with hip osteoarthritis who have not improved with medicines and physical therapy.

Is this trial a fit for you?
✓Likely a good fit
Adults with radiographic hip osteoarthritis who have had hip or groin pain greater than VAS 5 for more than six weeks and who did not respond to analgesics and physical therapy are ideal candidates.
✕Probably not a fit
Patients with lumbar radiculopathy, axial back pain, sacroiliac joint disease, connective tissue disorders, recent additional analgesic or interventional procedures, or inability to attend follow-up are unlikely to benefit or be eligible.

What this trial studies
This interventional, single-site study applies ultrasound-guided pulsed radiofrequency (pRF) to the articular branches of the femoral and obturator nerves in patients with chronic hip pain from osteoarthritis. Participants who failed conservative care and have significant pain will receive the procedure and be followed at 2, 6, and 12 weeks. Outcomes include pain measured by the Numeric Rating Scale (NRS) and function measured by the Oxford Hip Score (OHS). The procedure is performed without radiation and is intended as a minimally invasive option to reduce pain and improve mobility.
Why it matters
Potential benefit: If successful, the procedure could reduce hip and groin pain and improve function, potentially delaying or avoiding joint replacement for some patients.
How similar studies have gone: Thermal radiofrequency neurolysis of target nerves has shown positive pain relief but carries risk of neuritis and neuroma, while pulsed radiofrequency to these articular branches is a newer, less destructive approach with limited but encouraging preliminary data.
