According to Lilbet (and now I'm really sorry I don't remember where she said it, probably in one of her posts abotu her treatment in Germany) the injury is chronic - means that she has the problems for some time. Having chronic troubles doesn't mean you have problems requiring permanent "nursing", it requires regular examination. Again, it should be reminded that such injuries are not rare in any sport and the athletes continue their careers.
So, really please not incite anything, it was Lilbet herself, who pretty passionately defended her coaches from blaming about "ruining her career" and other love ltetters.
