Thank you Chris for the supportive words to chicagolinda. I really needed to hear those words and hope they give confidence to others. I have recently had Covid which has taken all my energy, but slowly recovering. I will be 79 in April, have RA and normally pretty active other than my knees holding me back. I am scheduled to have TKR in June, and will be doing my 6 weeks of PT required by Medicare to hopefully rebuild all I lost with Covid. It will be robotic with a highly recommend surgeon in Scottsdale. My daughter has ordered an ice machine and leg support pillow for me. I am feeling more confident after reading your supportive words. Thanks! Judith
