My surgeon uses robotic surgery and cryoanalgesia done at the time of surgery. This numbs the leg for about three months and there is supposed to be no pain the day of surgery. It didn't work quite right on me but kicked in a bit late, leaving me in pain in the recovery room and unable to move my leg at all when physical therapy came to get me up. By the next day, however, I was up and about and pain free for the most part. It's a strange feeling. My whole leg felt heavy and tingly, and that gradually subsided over several months. At 7-months out, just my knee feels tingly, and my surgeon said that will probably never go away. I had in-home PT for six weeks, followed by out-patient PT until I was a 6-months out. I'm continuing to improve as healing happens without doing anything special.
