My name might give you some idea of my thoughts on a TKR!
I need both doing but bizarrely, the one which started off as being OK, is the ne which needed the op and had needed it for many years.
My OS said the same as yours. 'You will know'.
And I did. I was beyond scared. I was petrified every time I thought about it. The pain, the rehab, the immobility, the reliance on opiates...you name it, I was petrified of it.
The reality has been very different. Yes I have a very high pain threshold but yours must be reasonable to have put off any op. The pain was controlled and I was off most of the opiates by two weeks. Rehab was VERY uncomfortable to start with and I ignore two exercises which REALLY hurt.
I am a carer so needed to be mobile asap. I had a freind stay with me for four days until I realise I could cope.
I batch cooked for the freezer as I was told I wouldn't be able to cope in the kitchen for a while.
Well I was cooking a full meal as soon as my friend had left. OK, sitting on a stool at times but I coped.
I went with my physio's advice and we started on gentle rehab a week after the op and I haven't looked back.
Ice will be your friend. This forum will be your venting place and your relatives, whoi should be primed to know this op is MAJOR and comments such as 'I thought you'd be OK by now' should be left until at least six months have passed
I was op ready fit, I am regaining that fitness but as one who needs the other knee doing, there is NO way I would have coped with a bilateral.
Even now, I won't contemplate the other knee at the moment. I said neverf again four months ago, now it's 'I'll see how I go'!
Good luck.
