About this study
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
In our clinic, patients undergoing pulsed radiofrequency treatment of the femoral and obturator nerve articular branches under ultrasound guidance for pain management due to hip and groin pain associated with hip osteoarthritis will have the efficacy of these methods on pain compared with the Numeric Rating Scale (NRS) and Oxford Hip Score (OHS) at 2, 6, 12 weeks.
Read the detailed description
Osteoarthritis of the hip joint is a common cause of pain and disability. Patients who do not respond to conservative treatments such as painkillers, physical therapy, and exercise often cannot undergo joint replacement due to comorbid conditions, while some patients prefer to postpone surgery as long as possible. Pulsed radiofrequency treatment applied to the articular branches of the femoral and obturator nerves, which innervate the joint, is a new technique for reducing hip joint pain. Previous studies have reported positive results after applying thermal neurolytic radiofrequency to the target nerves; however, this approach carries the risk of neuritis and neuroma formation. In our study, we aimed to investigate the effectiveness of pRF treatment applied to the articular branches of the femoral and obturator nerves under ultrasound guidance on pain and functionality in patients with chronic hip pain associated with osteoarthritis. The fact that the procedure is performed under ultrasound guidance, does not involve radiation exposure, and is an accessible and easy-to-perform technique makes it preferable for both patients and physicians.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ultrasound-guided femoral and obturator nerve articular branches pulsed radiofrequencyProcedure or surgery
Hemodynamic monitoring is provided. The hip joint where the procedure will be performed is cleaned with povidone-iodine. Sterile draping is performed. For PRF application to the articular branches of the femoral nerve, a convex ultrasound probe is first used to locate the articular branches of the femoral nerve in the groin area, followed by the articular branches of the obturator nerve. The radiofrequency cannula is inserted sequentially into the target points and sensory feedback is obtained. Then, a pulsed radiofrequency current, which has therapeutic properties for chronic pain and does not damage tissues by exceeding a temperature of 42 degrees, is applied to the relevant nerve root for 240 seconds. Subsequently, an injectate consisting of 2 cc of 5% bupivacaine, 4 mg of dexamethasone, and 2 cc of physiological saline is administered to the same nerve.

What is being measured
The primary outcome is the main question the study is designed to answer.
numeric rating scale
The numeric rating scale (NRS) is a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-10 scale, with zero meaning "no pain" and 10 meaning "the worst pain imaginable"
Measured: Change from baseline to 2nd 6 th and 12th weeks after treatment
Secondary outcomes (1)
oxford hip score
The Oxford Hip Score (OHS) is a joint-specific, patient-reported outcome measure designed to assess disability in patients witth hip osteoarthritis
Measured: Change from baseline to 2nd 6th and 12th weeks after treatment
