@ramona51 I am having a radio frequency ablation of my right knee on 11/20, for the same reasons. Yes, have gone through cortisone shots, plus various topical applications of different types of creams and lotions. It is the same for me, severe arthritis, and I am not a good surgery candidate for anything. They have previously done a genicular nerve block to see if there was relief, before submitting the paperwork to insurance for approval.

Good luck on your procedure! I will be anxious to hear how it all goes for you!
