I had TKR surgery on my right knee June 30, 2022. While I could do one stair at a time after just a few weeks, I wasn't able to do stairs normally until October, so about 3 months out from my surgery. In addition to PT at home, I did outpatient PT for about 6 weeks and they worked with me on specific exercises for climbing stairs. I have learned everyone recovers at a different pace, so be patient with yourself. You'll get there!
