I had the typical TKR and not robotic. I think it depends on the surgeon. Mine has done thousands of TKR and I am happy. The first few months were hard. At 7 months I'm doing everything I did and more. Yes, I still do too much and get sore by the end of the day but I'm getting stronger and things are moving along. It takes 6-12 months. yesterday I got on my hands and knees on the floor and got up on my own. I have no numbers anyplace and all my feeling has come back as well. My opposite foot Think has some issues with the top and ankle hurting but I might have favored it some. It's ok to be apprehensive. Just make sure you have a really good surgeon that I think that is the main key. You've got this.
