Thankfully the second time is easier!

Stairs will come and I believe your right leg will strengthen again, as your weight is more evenly distributed now. Righty may have taken on more as your left knee deteriorated.
Continue heel-toe walking for your gait.
Glue - if patience is not your strong suit

and you want the residual glue gone, you can try Isopropyl Rubbing Alcohol to dissolve the adhesive, applying a small amount with a Q-Tip, letting it sit briefly and then rub with the Q-Tip to gently remove, staying away from incision.
If you don't achieve the desired result, you can also try the same with Coconut Oil, Vitamin E Oil, or Olive Oil via the same process, apply, let sit briefly, then rub gently staying away from the incision. If you try any of these methods and they do work, please let us know for the benefit of others.
I didn't use any of the methods suggested above, but instead, in the shower soaped up the area with any residual adhesive and turned away from the shower stream, washing hair then body allowing the soap to dissolve the adhesive a bit, then I'd rinse and lightly / carefully scratch it off with my fingernail.
Glad to read you're a Happy Hippie Chick and you've been having a good Summer.

Thanks for the update!
