As I'm sure you know, if the knee cap is merely fractured but the integrity of the cap isn't compromised (as in my case), the healing time is much shorter. (I think I was on crutches for about 6 weeks; the walking pain persisted for some time afterwards.) But if the cap is broken through, that's another story entirely.
That would make sense Nova... and thanks for bringing that up. She's is making this out to be some HUGE injury that will persist with her for forever... knee injuries, as I am sure anyone here will say, HURT like the dickens! I have heard people say they can tell when the weather changes in them! So, she might have some persistent pain or general "discomfort" that is part of the healing process or that she might just have. It would really depend on the injury and the extent of it... and the treatment she received. For anyone who hasn't studied anatomy or who hasn't had a reason to look at the anatomy of a knee, go look it up... it is HUGELY complex.
Some injuries have tendon / ligament involvement as well, which can lengthen healing time. Of course, that's speculation, but the article said that she slipped, fell, and stood back up on it again. Gosh, that had to hurt. So, that makes me wonder what all happened to her leg. But to be cleared for a police officer job in two months (vs a secretary at a desk job) would make me think that her injury was not a HUGELY extensive knee injury... does that make sense? Because some injuries, like I said, for active people... completely take them off the job for a lot longer. I would think, just guessing... that for a police officer with an active job... that they would want her completely healed and ready to go before throwing her back out there. These guys are like investments. Unless they put her on desk duty (which is possible).
Due to the nature of her job (she was, apparently NOT someone who has a desk job... she was active in the field, and I did not note that she went back to one) she would have needed to be cleared in full before she went back to work. I would have liked to have seen the reporter expand upon this "broken knee" thing... people say "my knee is broken" and it can mean a LOT of different things. I am sure it was fractured, or he would have said otherwise. But, I have had people say "my knee is broken" when it is tendon and ligament injuries because they really don't know any better. Of course, then, I work with kids a lot

. So, if it doesn't work, its broken!
But the knee is a complex joint... you could have the cap compromised, the tendons or ligaments, surrounding tissues and bones... and if any of those are injured and the knee is involved, people could many times lump that in with "broken knee". I think that is going to be a major component of determining if this is fivolous!! I think it is... that's my personal opinion. From reading the little articles I did.
From the article I read, she received workmans comp and is now going after the family.

If she were able to return to regular duty (running, jumping, doding bullets!) she must... come on, had to have been cleared by workmans comp... usually, that's pretty strict with police officers, right? Why is she avoiding going after them? I was reading after I posted earlier, actually, in one article that she was a GREAT worker... I know I said she must have been otherwise, but one recommendation was that she should be the next leutinent! One of her coworkers (maybe a superior?) advised her not to file the lawsuit, but she did not listen. Apparently her personel file is filled with glowing recommendations. That's sad, in a way, but I think she should have listened. She's letting greed get to her (IMO). This will follow her forever.
Ok. I'm done rambling now. Hope that made sense!
