Was done in central NJ, (Seaview ortho), and I would not have had it done, but hindsight is 20/20. I just had three disks in my back replaced, and it may come out OK, so far so good. PS the knee surgeon was supposed to be the best guy around, had more stars in reviews then a 4 star general. and he still managed to screw me up. My advice is to try everything before letting them cut on you, I thought knee surgery was not a big deal, I was wrong!
