Best wishes for a comfortable recovery. I had BTKR and returned home from the hospital on day #3. I have 15 stairs, and was able to do them safely without problem. Going up was slow, but not too painful. I found that going down sideways felt safer and was easier for me. The first week or two, I only went up and down once during the day, but probably could have done more if needed. Please let me know if you have any questions - and good luck!
