@Ewok , I know our nurse, Josephine went home alone and lives in a 2 story house. Like you, I went to a rehab until I could do the 13 steps to my home. This time though you’ll have a good knee (TKR) to use on the steps. Why don’t you try just using your TKR leg to climb the stairs, bringing your ouchy non-TKR leg up to the step. If you can do that now I imagine you can after surgery.
