GOOD LUCK Jaye.
If courage flags a bit, think of England's Queen Mum's hip replacements! She had two of them, and I remember a little vignette of her in a film clip of a church service: There was a lot of standing up and sitting down - and the Queen Mum was up and down and up again as quickly and as easily as the young people aroud her - and that was with two new hips - and she must have been well over thirty years older than you at the time.
Royal hips or real people's hips - the replacements really work.
I paid attention to it because it was quite jealous-making. I can't get up without a major struggle.

Mend well and quickly.

The very best wishes from birte
