You can pass a medical. Be 100% fit at this moment in time. But from what I read there was some concern over the knee not that it was broken. So he passed his medical unless you want to be picky?
You don't pass a medical to check if you are fit but rather to see if you have a problem that increases your risks of getting injured. A number of players passed their medical while being unfit to play as they were recovering from an injury. It's not being picky but what you check when you pass a medical. It's not like a medical check up.
