@klarnold, I had my right TKR done in April 2019 and when I first looked into TKR I was hoping to have the computer assisted surgery but my Mayo surgeon was not one who uses it for knee replacement surgery. I am extremely happy with my results though. I had a friend who just had her knee replaced at the same Mayo location using the computer assisted surgery and it went really well also. She is excited to have her other knee done soon. Here's some information on the topic from 2018 that you might find interesting.
