Hi @mhort1213 - I had one knee done in April 2017 by the old technique and one done in January 2019 by the new robotic assisted technique. My doctor was very interested in my experience since I was a living, breathing, AND walking example of before and after! The surgeon told me that the surgery was more accurate and that he had been told that the robot assisted surgery results in less pain and a quicker recovery - since they don't have to cut as much bone . That was so true for me. I was able to stop my pain meds about a month earlier on my second knee and I reached all of my milestones much more quickly. For example, on my 2nd knee, before my discharge from the hospital, I was so steady using the walker that the physical therapist let me try using a cane. I was fine. I actually did use the walker of and on for about a week once I was home - especially at night to go to the bathroom, but most of the time I used a cane. Then, by week 2, I was not using a cane or walker in the house - only outside. At the beginning of week 3 I was allowed to drive and by mid-week I transitioned from inpatient PT to outpatient. At that point, my ROM was great - I had full extension and my flexion had reached about 128. My outpatient physical therapist concentrated on balance and functional activities like stair climbing since we didn't really need to work anymore on ROM. I was discharged from PT at 8 weeks (as opposed to 12 weeks with my first knee). So... I'm a huge cheerleader for the robot assisted arm surgery. I'm going to share a link that talks about this technique. Is there anything you are particularly worried about with the surgery? I'll be happy to share any additional information I have if it will help. Meantime, check this out - Dr. Ortiguera was my surgeon and he is terrific:
