You mean Tara. Yes, already as a teen she was having a lot of pain. She fought through it long enough to win the Olympics. This was a factor in her decision to leave eligible skating at 15. After touring with SOI for a few years she had to call it quits.
In Tara's case the primary blame was put on her endless repitions of the triple loop / triple loop combination in practice. As I understand it, the loop jump is especially hard of the hip joints.
Maybe the hinged boot (favored by Alissa Czisny, among others) will help to reduce this kind of injury.
