The First to Bring Ultrasound-Guided Cooled RF to the Knee*

* with level 1 clinical data

Finally, physicians can manage long-term relief of OA knee pain with an ultrasound-guided procedure that is:

  • Clinically proven to provide up to 12 months of pain relief1
  • Non-narcotic
  • Minimally invasive

COOLIEF* Cooled RF – the first cooled RF treatment for chronic OA knee pain – is now the first to bring ultrasound-guided cooled RF to the knee

The Ultrasound Knee technique for COOLIEF* Cooled RF has 3 target locations with the 4th location being optional. The technique for the diagnostic block under ultrasound is the same as the technique for COOLIEF* Cooled RF of the knee.

Target Locations:

  • Superior Medial Genicular Nerve
  • Superior Lateral Genicular Nerve
  • Inferior Medial Genicular Nerve
  • Suprapatellar Genicular Nerve (Optional 4th Lesion)

If you have an ultrasound unit, you can perform ultrasound-guided, COOLIEF* Cooled RF.

Benefits include:

  • No radiation
  • Real-time guidance
  • Soft tissue visualization (including effusions)
  • Doppler (genicular nerve visualization)

Clinical Data§ supports COOLIEF* Cooled RF for treatment of OA knee pain2

Randomized level-one, multi-center study with 151 patients over twelve months with primary effectiveness at six and twelve months

COOLIEF* Cooled RF Fills the Gap Between Short-Term Pain Relief and Surgery

† Patients with patellofemoral compartment symptoms potentially could be candidates for the 4th lesion – Suprapatellar Genicular Nerve – provided they respond well to the diagnostic block.
