I was worried about the surgery

My concern about my operation was that it could go wrong.

I spoke to someone, who told me that I certainly shouldn't do it unless it was the only option left.
Some people told me how badly it could go, that perhaps I would end up in a wheelchair.

Or something could happen during, such as infections.
It could actually become worse than it had been.
I consider that, and I decided that it could well be that it could be worse, but it was so bad that I couldn't do anything else.

I had to focus on that hopefully it wouldn't get worse.

The advantages outweighed the possible disadvantages.
And yes, one does get afraid when going for any bodily intervention.

When we were at the hospital and saw the mechanical piece, it was strange to think that it was going to be implanted and would replace parts of my body.
But I also had to focus on that I couldn't go on the way I was.

Something had to be done, and yes, if that was getting a new hip - then that was that.
