I have the same issue with arthritis. It's everywhere. I recently went from 189 lbs to 160 lbs, well it took me a year and a lot of time in the spin studio. I also cut out 90% of refined sugar products, a major cause of joint inflammation. (I should cut out 100% of sugar, but I love a coke now and then, and a desert once in a while.)

I did have both knees replaced in 2022. Best thing I've ever done. My hips and shoulders are bone-on-bone, but I have no pain.

msjv asked what caused damage to the acetabulum. Well this socket is lined with cartilage. Arthritis and bone spurs wear away this cartilage, and the same thing happens on the head of the femur. And that results in bone moving against bone. And cartilage cannot be replaced.

Anything we can do to reduce inflammation - diet comes first, maintain a weight appropriate for height, exercise - especially cardio - and these are all things we mostly control.

And in the worst case - well for shoulders, hips, and knees - surgical replacement is very advanced. There is no reason to live a life in pain.
