I had my left knee done in January of 2021….right knee TKR with ceramic also last July 2022…in January I made a trip to my daughters house in Omaha….she has a three story house….now mind you, when I went, in order to go up and down her stairs I would have to go one step up and bring my other foot up, then foot up and other foot up…..also, to get up from a chair, toilet or whatever I would have to put my hands on something and push myself up…. After walking up and down her stairs for 2 weeks (she had me painting bedrooms upstairs and down) so also up and down ladders…I can now lift myself up, no hands also go up and down stairs just like a regular person who never had replacements…it’s great! As they say, exercise is your friend and they made a believer out of me!
