Nerve branches to the vastus medialis added to genicular nerve treatment for chronic knee pain

Official title: Chronic Knee Pain Beyond the Genicular Nerves: The Role of Distal Sensory Branches of the Nerve to Vastus Medialis

Run by Diskapi Teaching and Research Hospital · NCT07703293 · Data updated 2026-11-12

This observational study tests whether adding pulsed radiofrequency to the nerve branches near the vastus medialis to standard genicular nerve treatment helps people with chronic knee osteoarthritis pain.

Is this trial a fit for you?

Likely a good fit

Adults 45-80 years with knee osteoarthritis (Kellgren-Lawrence grade II-IV), chronic knee pain for ≥3 months, and insufficient response to conservative therapies.

Probably not a fit

Patients whose pain is not driven by the distal vastus medialis sensory branches or who do not respond to any radiofrequency approach may not see additional benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational cohort study enrolling adults aged 45-80 with clinically and radiologically confirmed knee osteoarthritis and chronic knee pain (≥3 months) who have not fully responded to conservative care. Participants will receive either conventional genicular nerve radiofrequency alone or with additional pulsed radiofrequency targeting the distal sensory branches of the nerve to vastus medialis, and will be followed in routine clinical practice. Outcomes include pain measured by the Visual Analog Scale and function via the WOMAC score, assessed at baseline, 1 month, and 3 months after the procedure. The study aims to compare outcomes between the two treatment approaches and monitor safety events related to the procedures.

Why it matters

Potential benefit: If successful, patients might experience greater pain relief and improved function with an expanded radiofrequency approach.

How similar studies have gone: Prior anatomical and ultrasound studies support the role of additional sensory branches, but direct comparative clinical data are limited and this observational approach is among the first to contrast these two strategies.
