I went through my replacement knees with Jane10 for support - thanks Jane! Bonesmart is an excellent site for support and information. I have no regrets whatsoever.
Before I couldn’t manage slopes and struggled to walk 500 yards. Yesterday, my phone step counter tells me I walked 13,572 steps! (I was sightseeing) Yes, the aftermath is painful which is not surprising when you consider what’s been done, but most of the pain was from my tendons and muscles re-adjusting to being where they should be. I do still use a hike stick occasionally but only for confidence as I’m still getting used to having two feet pointing in the same direction!
I would only add what my surgeon told me, which was to pretty much ignore the physio excercises and just potter as much as you can. Push a little further each day and only bend the knee until you felt it. With my first knee the physio told me I could bend it much further and pushed my knee hard. I felt the stitches give way. The scar shows it.
BBbevan the knee giving way is one of the indicators that your DH really needs to start the process. In my area of the UK this starts with six sessions of physio. It doesn’t make the slightest difference but it’s part of the process.
