@guidant07, I've been to several appointments at my local Mayo Family Clinic and I have one scheduled for tomorrow at Rochester Mayo Clinic to get a 24 Holter monitor connected. Mayo is really on the ball for protecting both employees and patients. Masks are required and they also check your temp and ask you COVID-19 screening questions before you gain entrance to the buildings. It's certainly much safer than going to Costco or your local grocery store 🙂
Good luck on your knee replacement. I just had mine done a year ago April at Rochester Mayo Clinic only at the Methodist building. They are really good and will take care of you. Just make sure you follow the physical therapist and the surgeon/care team's instructions to make sure all goes well with the rehab. I did my rehab at home and was quite happy that I could do it at home.
