Radiofrequency Ablation (RFA) of the knee

Candidates for radiofrequency ablation of the knee are typically individuals suffering from chronic knee pain that is not adequately controlled by conventional treatment methods such as medication or physical therapy.

Preparation for the treatment involves reviewing medical history, conducting a physical examination, and explaining the procedure itself and potential complications.

During the treatment, the patient lies on the procedure table, and the treatment area is sterilized. Local anesthetic is applied to the skin to reduce discomfort during the injection of radiofrequency energy. Then, a thin needle or catheter is inserted through the skin and guided by fluoroscopy or CT to the treatment site. Once the needle is properly positioned, radiofrequency energy is used to heat and destroy the nerve endings responsible for pain.

Results of knee radiofrequency ablation may vary, but many patients notice a reduction in pain and improvement in function after the procedure. It is important to note that the results may be temporary, and some patients may require repeat treatments to maintain pain relief.

Precautionary measures include monitoring for potential complications such as infection, bleeding, or nerve damage. Patients should follow their doctor's instructions regarding activities after the treatment to avoid complications and ensure optimal healing.
