Found a follow up - actually 10 months after replacement, not 19.
Hi TKR 19 months ago.I can kneel on a bed or sofa easily, any type of floor is possible but uncomfortable., getting up is an effort usually requiring a piece of furniture to hang on to! My 'good' knee sometimes reminds me I was told it would need renewing. I've not lost weight which I know would help. I'm active and walking quite a lot with a stick which I think is mainly for confidence. I can't carry anything easily without the stick.
I'm still slow on stairs in tube and railway stations etc. I tend to go sideways. Escalators are fine. Going down hill is a bit precarious if steep and/or rough ground, going up is slow but fine.
I'm sad not to be able to have a bath but showers are all right even though mine is over the bath, DD's walkin is bliss!
Arthritis is increasing in my right hand.
Overall I'm fine and, from my experience, would recommend TKR. My activities were becoming severely curtailed before I had mine done. Hydrotherapy help me afterwards as did the physio exercises which I still do though not every day.
