Well, this is a fairly common scenario, Trician, and it's really down to comparing how much you are having to give up with how badly you want to do those things.
It's a sad fact that we, all of us, have coped with our problem knees by slowly contracting our lives, dropping this activity or that, declining invitations, staying home when we would have gone out for a walk. Little by little our lives get reduced and contracted until they are but a pale shadow of what they once were. And it all happens almost subliminally so we are hardly aware of what we are losing.
Fact is, it's so much easier to make the decision when the pain is excruciating and one can hardly put weight on it. But most knees don't go like that. It's 'salami tactics', slice by slice, and pretty soon we look back and wonder where our life went! Beware of that.
So what I am saying is, you need to assess your life. What took you to the surgeon in the first place? How much can you do that you want to do? And just how much pain are you really in?
Take me, for example. There was some evidence of damage in the x-rays but not a huge amount. I had limited pain only but achieved that by not doing a lot of things I would have done. But I'd have episodes of bad, sharp pain when a bit of debris got in the wrong place inside the joint and I would end up on crutches for a week or so, convinced that life as I knew it was over. Then I'd wake up one day and find it was fine again. After three or four of these episodes, I decided to get the knee done before it got any worse and I had to lose more of my life. Surgeon raised an eyebrow but conceded that "it wasn't going to get any better" and so we went ahead.
On the other hand, my sister delayed and delayed. Her x-rays were ghastly! Lots of arthritis and bone damage but she still prevaricated and ended up being rushed into hospital with a locked knee and pain so bad she had to spend a weekend on a morphine pump! I determined I wasn't going to risk that and decided sooner rather than later, even though I knew what happened to her doesn't happen very often.
In the end, the choice is yours. But will it be worth it? Well, you'll be pain free eventually and able to resume normal activities, if that helps!
