About this trial
This observational cohort study aims to evaluate the clinical effect of adding ultrasound-guided pulsed radiofrequency treatment of the distal superficial and deep sensory branches of the nerve to vastus medialis to conventional genicular nerve radiofrequency treatment in patients with chronic knee pain due to knee osteoarthritis.
Adult patients aged 45-80 years with clinically and radiologically confirmed knee osteoarthritis and chronic knee pain lasting at least 3 months despite conservative treatment will be included. Patients will be followed according to routine clinical practice. Two cohorts will be evaluated: patients treated with conventional genicular nerve radiofrequency alone and patients treated with conventional genicular nerve radiofrequency plus pulsed radiofrequency of the distal sensory branches of the nerve to vastus medialis.
Pain intensity will be assessed using the Visual Analog Scale, and functional status will be evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index. Assessments will be performed before the procedure, at 1 month, and at 3 months after treatment. Adverse events recorded in patient files will also be evaluated.

Trial population
The study population will consist of adult patients aged 45 to 80 years with clinically and radiologically confirmed knee osteoarthritis and chronic knee pain lasting at least 3 months despite conservative treatment. Eligible patients will be those who are evaluated in the Algology Clinic and undergo ultrasound-guided genicular nerve radiofrequency treatment, with or without additional pulsed radiofrequency treatment targeting the distal sensory branches of the nerve to vastus medialis, as part of routine clinical practice. Patients will be included after providing written informed consent and will be followed for pain and functional outcomes at baseline, 1 month, and 3 months after the procedure.

Treatments tested in this trial
Conventional Genicular Nerve Radiofrequency
Procedure/SurgeryUltrasound-guided conventional radiofrequency treatment targeting the genicular nerves will be performed as part of routine clinical practice in patients with chronic knee pain due to knee osteoarthritis. Pain and functional outcomes will be evaluated using the Visual Analog Scale and WOMAC scores at baseline, 1 month, and 3 months after the procedure.
Conventional Genicular Nerve Radiofrequency Plus Pulsed Radiofrequency of the Distal Sensory Branches of the Nerve to Vastus Medialis
Procedure/SurgeryUltrasound-guided conventional radiofrequency treatment targeting the genicular nerves will be combined with pulsed radiofrequency treatment of the distal superficial and deep sensory branches of the nerve to vastus medialis. This combined approach will be performed as part of routine clinical practice in patients with chronic knee pain due to knee osteoarthritis. Pain intensity and functional status will be assessed using the Visual Analog Scale and WOMAC scores at baseline, 1 month, and 3 months after the procedure.

Trial outcomes
Primary outcomes
1
Change in Visual Analog Scale Pain Score
Change in knee pain intensity measured using the Visual Analog Scale. The score ranges from 0 to 10, with higher scores indicating more severe pain.
Time frame
Baseline, 1 month, and 3 months after the procedureSecondary outcomes
1
Change in WOMAC Score
Change in knee osteoarthritis-related pain, stiffness, and physical function assessed using the Western Ontario and McMaster Universities Osteoarthritis Index. Higher scores indicate worse symptoms and functional impairment.
