I'm sorry your wife passed. It's certainly a difficult time for you. My TKR recovery has been slow with many ups and downs and weird sensations that move to different parts of my body.
At 10 months I still have a hard time with stairs so I avoid them as much as possible. My quads are still weak so I turn to stone if I stand for a long time, lol.
I have not had a quick and easy recovery, but I
have never had problems sleeping. Thank goodness!
Check with your surgeon, mine does a lot of MRIs to make sure the implant is OK. My surgeon 's assistant told me recently that some people take up to 2 years to fully recover.
