I’ve had both knees done, in October last year and January this year. I’ve had a fair few surgeries in my life, I also have four children, knee replacement is without a doubt the most painful thing I’ve ever been through.
You are absolutely on the right track with strengthening exercises! Motion is lotion! Many people can and do get along quite well, bone on bone for many years.
I asked my surgeon about skiing before surgery, he said gentle skiing was fine, maybe give the black diamond runs a miss, but he wasn’t keen on anyone running (but pickleball and tennis are okay).
I’m in Australia, but between the two surgeries, I found a brilliant physio group who specialises in knees. Strengthening my muscles around the knees and my quads between the two surgeries, meant that my second recovery was a lot better than my first. See if you can Google and find someone near you and absolutely join that Facebook group. I’m in a similar one here.
As for waiting longer, do it if you can, but just don’t wait until you’re eighty! I’m 60 and it was hard, watching some people in their 80s trying to recover is hard just to watch. But don’t wait until you are immobile, those people have a rough recovery too.
It’s hard finding that balance. My knees done still have pain and a lot of tightness through the scar area. But the pain is different now, not in the joint itself, it’s in the tissues around the new joint. That said, I no longer take any pain relief and I do find that movement helps.
Am I glad I did it? On balance, yes. Give it another six months and I’m hoping I’ll feel even better about it. Mine was the robotic surgery, so it’s precision stuff, but it won’t ever be the same as a real knee.
