Don;t be a fat, carb feasting, non exercising slob and you can cut your risk of this kind of maladay. Look at the data, 80%+ of knee replacement are on morbidly obese.
I’ll be in that 20 percent in a few years.
I fell and hurt my hip about 14 years ago. Had a hip replacement 2 years ago on my 60th birthday. Now, my other hip has moderate arthritis and starting to be very painful.
The knees are bad too because of all the hip problems. I also have some weird congenital knee problems when my knee cap is small and floats around more than it should.
I find exercising is really helping the knees, but not doing much for my natural hip.
Sometimes people with joint problems gain weight because they have so much pain that even mild exercise is impossible. You are very compassionate, aren’t you?
