@ellerbracke First, please excuse all the typos above. I was on sedatives when I wrote that (they didn't help a lot during the procedure!). The point is to disconnect the nerves in four spots, which supposedly will decrease pain after the TKR, since they take 6-9 months to regrow. Some doctors actually do knock you out for the ablation, but my dr. said you are just going approximately in terms of the four spots if you do that. So I had to gut it out. They also have to be very careful not to ablate any motor nerves, which will affect walking. So they have to text first for reaction, by putting in a small current and asking if you feel it, then to see whether they have hit motor nerves, by asking if you feel anything up and down the leg when the current is on. My dr. said people rave about the pain reduction post-surgery and say they are able to get off drugs much quicker. I suppose some have had more than one TKR and can compare. Well, we'll see!
