Genicular Nerve Cooled Radiofrequency Ablation (Cooled RFA)<\/strong><\/h3>\n

If chronic knee pain is limiting your movement and conventional treatments are no longer delivering adequate relief, Genicular Nerve Cooled Radiofrequency Ablation (Cooled RFA)<\/b> is an advanced non-surgical treatment that provides long-lasting pain relief \u2014 with a broader treatment zone than standard RFA, and a recovery time measured in days rather than months.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

What Is Genicular Nerve Cooled RFA?<\/strong><\/h3>\n

Standard radiofrequency ablation generates heat concentrated at the tip of the needle, producing a relatively small, elongated lesion. Cooled RFA incorporates an internal water-cooling system <\/b>within the probe, which actively manages tip temperature. This prevents overheating at the tip and allows significantly more radiofrequency energy to be delivered safely into the surrounding tissue \u2014 creating a larger, more spherical treatment zone <\/b> that covers the genicular nerves more completely.<\/span><\/p>\n

At the knee, the genicular nerve anatomy varies between individuals, making complete nerve coverage with a small treatment zone unreliable. Cooled RFA's broader ablation area substantially improves the likelihood that all relevant nerve branches are effectively deactivated, resulting in more complete and durable pain relief.\n
<\/b>\nCooled RFA technology is approved by both the US FDA<\/b> and the Thai FDA (\u0e2d\u0e22.)<\/b> and is used as a standard of care in leading pain management centres worldwide.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Who Is This Procedure Suitable For?<\/b><\/h3>\n
\u00a0<\/b><\/div>\n
    \n
  • Chronic knee osteoarthritis<\/b> \u2014 patients with ongoing knee pain from joint degeneration, particularly those who are not yet ready for knee replacement surgery or who prefer to avoid it<\/span><\/li>\n
  • Persistent pain following knee surgery <\/b> \u2014 including patients who have undergone total or partial knee replacement but continue to experience significant residual pain<\/span><\/li>\n
  • Patients resistant to conventional treatment<\/b> \u2014 those who have tried oral medication, corticosteroid injections, hyaluronic acid (viscosupplementation), and physiotherapy without achieving adequate pain control<\/span><\/li>\n
  • Patients seeking a non-surgical, medication-reducing option<\/b> \u2014 for those who want to reduce ongoing reliance on pain medication and achieve longer-lasting relief without major surgery<\/span><\/li>\n<\/ul>\n

    \u00a0<\/p>\n

    \u00a0The Procedure<\/strong><\/h3>\n
    \u00a0<\/strong><\/div>\n
      \n
    • The procedure is safe, precise, and typically takes 45\u201360 minutes<\/b> depending on the number of nerves being treated.<\/span><\/li>\n
    • Real-time image guidance<\/b> \u2014 the physician uses ultrasound guidance and\/or fluoroscopy (live X-ray) <\/b>to precisely locate each genicular nerve target around the knee in real time, confirming accurate placement before energy delivery<\/span><\/li>\n
    • Cooled ablation <\/b>\u2014 fine cooled probe needles are advanced to each target nerve position; radiofrequency energy is delivered through the water-cooled system, creating a larger treatment zone than standard RFA and ensuring effective deactivation of the genicular nerves responsible for knee pain<\/span><\/li>\n
    • Total procedure time is approximately 45\u201360 minutes depending on the number of nerve targets treated.<\/span><\/li>\n<\/ul>\n
      \u00a0<\/div>\n

      Expected Outcomes<\/b><\/h3>\n
        \n
      • Significant and sustained pain relief <\/b> \u2014 most patients experience a meaningful reduction in knee pain; the therapeutic effect typically lasts 6 to 24 months<\/b>, with individual variation depending on the severity of the underlying joint condition and the patient's overall response<\/span><\/li>\n
      • Improved mobility and function<\/b> \u2014 reduced pain enables patients to move more freely, engage more effectively in physiotherapy and rehabilitation, and return to activities they had previously been unable to perform comfortably<\/span><\/li>\n
      • Reduced medication dependence<\/b> \u2014 Cooled RFA helps patients significantly reduce or eliminate their reliance on ongoing pain medication, lowering the cumulative health risks associated with long-term analgesic use<\/span><\/li>\n<\/ul>\n
        \u00a0<\/div>\n

        Post-Procedure Care<\/b><\/h3>\n
        \u00a0<\/b><\/div>\n
          \n
        • First 1\u20132 days:<\/b> Mild soreness or aching at the treatment sites is normal and expected. This is a routine tissue response and typically resolves on its own within 1\u20132 days.<\/span><\/li>\n
        • Activity:<\/b> Most patients can return to light daily activities the following day. Avoid strenuous exercise or activities that place significant load on the knee for the first 48 hours following the procedure.\n
          <\/b>\n
        • Pain onset:<\/b> Full pain relief from the ablation develops gradually over 2\u20134 weeks as the nerve deactivation takes complete effect. It is normal to experience variable pain levels in the first 1\u20132 weeks before full benefit is felt.<\/li><\/span><\/li>\n<\/ul>\n
