Hi Jo I prefer the walker my self, after my scopes, it was hard to get around fro just a little while, Dr didn't give crutches or anything, as I suppose since the scopes are not as hard to recovery from a tkr. But for a a week or so it was hard, so my mother in law loaned me her walker for a little while.
i was on crutches for 6 months after he first patella dislocation in my knee when i was 12, I hated them so much, the hurt my arms alot.
I feel you should do what feels right for you, and not worry about what the physio thinks, if it makes you more confident and more sure footed then stick with it until you know you feel secure about using crutches or possibly straight to cane, without having to use crutches at all.
Goo luck with your recovery, you sound like you are doing very well.
Will continue to watch your recovery, take care...:flowerysmile:
