Babette: I am at almost 9 weeks post TKR, and still have some issues with stairs. Going up is tiring, but not really painful or a problem, even though I hold on to the railing for safety. Going down depends a lot on when I last exercised. I have access to an indoor salt water pool, and after those sessions I can absolutely walk down quite easily. Other times not so much. However, I had arthro clean-out surgery on the same knee 12 months ago, and even after 10 months I was unable to handle downstairs at all, so for me the current progress is very encouraging. Hang in there!!!
