The "damaged" hip is actually one of the two main features used to tell a theropod away from other dinosaurs. The theropods ischium is facing backwards, while their illium faces forwards. This is the ancestral configuration, although it was secondarily lost in the species most closely related to birds, which have *both* facing backwards,
Plant-eating Ornithischia, like the Triceratops, on the other hand, evolved that "new" hip configuration much earlier.
