Thanks JK-along with everything we are all going through, I haven't had the heart to comment, but now can reply. The ablation did not work, in fact it introduced more pain . I have been barely managing and then one month ago, the surgeon suggested one more shot, which was hellish and left my knee bruised and angry. The last shot was that he suggested a synovial ganglion implant and I ran. When will this suffering end... i've lost so much. Last resort, new surgeon suggests metal allergy test-which will be $400+ out of pocket as insurance doesn't cover it. The idea being that if it was so then a new total new knee replacement w/o said allerg yinducing components would -perhaps be a remedy. Any one else ?
