Future orthopedic issues?

Do you all think being a DCC and this level of pro dancing/cheerleader will cause these girls future orthopedic issues that may require surgery?

I feel like being a DCC is so physically demanding and must cause wear and tear. Even for girls who aren’t injured yet, I wonder what the effects will be when they are in their fifties, sixties, and beyond.

What do you all think? Hopefully none of this causes any long term damage!
