Interventions

  • Conventional Genicular Nerve Radiofrequency — PROCEDURE
    Ultrasound-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
    Ultrasound-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.

Study Details

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.

Arms

  • Arm: Conventional Genicular Nerve Radiofrequency
    Patients with chronic knee pain due to knee osteoarthritis who received ultrasound-guided conventional radiofrequency treatment targeting the genicular nerves as part of routine clinical practice.
  • Arm: Conventional Genicular Nerve Radiofrequency Plus Pulsed Radiofrequency Nerves Vastus Medialis
    Patients with chronic knee pain due to knee osteoarthritis who received ultrasound-guided conventional genicular nerve radiofrequency treatment plus pulsed radiofrequency treatment targeting the distal superficial and deep sensory branches of the nervus vastus medialis as part of routine clinical practice.
