Save Your Knees

A decade of arthritic knees, what actually helped me protect them, and the plain truth about replacement when I ran out of road.
Protecting arthritic knees, and the rehab that got me walking again.

Surgeon says my X-ray isn't bad enough for surgery but the pain is unbearable. Do they go on the scan or on me?

Some of you followed my injection saga. Update, and I'm a bit deflated. Had the surgeon consultation in late February that I'd been building up to for months. He was decent, examined me properly, and then more or less said the X-ray shows moderate wear but not the worst he sees, and that he wouldn't rush to replace it yet.

Which would be fine EXCEPT I'm the one living in the knee. It wakes me most nights, I've given up golf, I plan my whole day around not having to stand for long. And I'm sitting there being told the picture isn't bad ENOUGH, when the pain absolutely is.

So which is it? Does the decision go on what the scan shows or on how much the thing is wrecking my life? Because those two seem to be pointing in opposite directions for me and I came out of that room genuinely confused about whether I'm making a fuss over a "moderate" knee.

Brian, the thing that helped me here was learning that the scan and the symptoms often just don't match. There are people walking around with dreadful looking X-rays and barely a twinge, and people in agony whose films look middling. My consultant said the X-ray is one piece of information, not the verdict. Doesn't fix your pain, but it might explain why you weren't laughed out of the room, he clearly took the pain seriously or he'd not have examined you like that.

My brother-in-law (the tyre expert from the walking thread, he has opinions on everything) reckons they only operate once you're fully bone on bone and the X-ray is a wreck, and until then you just put up with it. Is that actually true? Because if it is then Brian's stuck, but it doesn't quite square with what I've read here about it being about your life not the picture. Genuinely asking, I might be in the same boat before long.

It's not true Sue, or at least it wasn't for me. Mine went ahead on how much it had taken over my life, sleep, the giving-up list, all of it, and my film was described as moderate too. What I'd say to Brian is the "not yet" isn't a no forever, and it isn't a judgement that your pain isn't real. It's a "the balance isn't there yet for me". Balances change. Mine did.

Straight answer to your actual question: it goes on you, not the film, but the two together. A good surgeon treats the person in front of them, not the X-ray on the screen, and the thing they weigh most is how much the knee is limiting your life, not the grade of wear on its own.

Here's the bit nobody explained to me until late: the match between what an X-ray shows and how much a knee hurts is famously loose. Surgeons often score the wear on a scale of 0 to 4, but studies keep finding only a rough link between that score and the pain: in many series only around half of clearly arthritic knees are painful enough to trouble the person. Plenty of severe-looking films sit under people who cope fine, and plenty of moderate ones sit under people in real trouble, which is exactly the gap you've landed in. So "not bad enough on the scan" is not the same sentence as "your pain isn't bad enough". What a surgeon is actually judging is the whole picture: night pain and lost sleep, the list of things you've stopped doing, how far you can walk, whether the injections have stopped working, and yes, the imaging as one input among those, not the boss of them. I went through the same "moderate knee" conversation and let it quiet me for far too long, when the honest measure was sitting in the list of things my knee had already taken off me.

A few concrete things that helped me. One, write the list down properly, the golf, the broken sleep, the day planned around standing, it's more persuasive on paper than in a ten minute appointment where you forget half of it. The site's guide to the signs you may need a knee replacement is essentially that list in structured form, and it leans on function and pain, not just the X-ray. Two, ask the surgeon directly what specifically he wants to see change before he'd operate, and what you should do in the meantime, so "not yet" comes with a plan and a review, not just a door closing. The questions to ask your knee surgeon piece has good ones for exactly this. Three, a second opinion is completely reasonable and not an insult to anyone; surgeons genuinely vary in where they draw the line.

What I can't tell you, and no forum can, is whether it's time for your knee. That needs your examination, your imaging and your history in one room. But don't let "moderate" talk you out of taking your own pain seriously.

Owed you all an update. Took Margaret's advice more or less to the letter. Wrote the whole list down, went back to my GP, asked the "what specifically needs to change" question and got a proper answer instead of a shrug, and I've been referred for a second opinion which is booked for August.

The night pain is the one that's decided me it's worth pushing. Nobody's promised me a green light and the second surgeon might say the same "not yet", but at least now I'm asking the question with the list in my hand rather than sitting at home deciding I'm making a fuss. Will report back after August. Slowly learning that "moderate" on a scan and "manageable" in real life are not the same word.
