Hi @lblazina, I had my right knee done at Mayo Rochester on April 5th and had a similar experience as @kajon. I wasn't quite as worried about the options but the anesthesiologist did a great job of talking me through them and about all I remember is being rolled into the operating room with all those bright LED lights overhead. Woke up feeling pretty good in the recovery room and like @kajon the nerve block on the knee wore off by the next morning and I was release around noon. Mayo does a great job addressing any concerns or fears you have.
