Genicular Nerve Block for Chronic Knee Pain

Cooled radiofrequency ablation of genicular nerves is a minimally invasive procedure used to manage chronic knee pain, particularly for patients with osteoarthritis or post-surgical knee pain, who have not responded to conservative treatments like physiotherapy or analgesics.

This technique is used to block genicular nerves, which transmit pain signals from the knee joint to the brain.

These are sensory nerves (only carry sensations) with no motor component (do not supply any muscles) and hence this technique carries no risk of post procedure weakness.

During the procedure, ultrasound guidance is used to precisely target these nerves. A needle-like probe is inserted near genicular nerves, and radiofrequency energy is applied to disable the nerve tissue.

This disrupts the pain signals without affecting motor function or causing significant tissue damage.

This procedure can provide significant pain relief, improving quality of life for these patients.

Since the success of the procedure depends on accurate targeting of the nerves, image guidance is of utmost importance.

This procedure is a minimally invasive procedure, requiring no incisions, which reduces the risk of complications and shortens recovery time.

Pain relief can last from six months to two years, depending on the stage of disease, patient factors and the extent of nerve regeneration.

It is not a cure for underlying conditions like arthritis, however is an excellent option for pain management in patients who wish to postpone the surgical treatment, do not wish for surgery, not fit to undergo a definitive surgery or post knee replacement pain.
