The transgender weightlifter has recently faced criticism from people who feel that she should not compete in the women's category.
Despite doing everything she could do to prove she deserved her place in the event, Hubbard was forced to endure repeated attempts to stop her from taking part.
"I don't think I am any different from anyone else, I don't think I am any tougher - I just do what I have to do", Hubbard said.
"I have no regrets about the attempts I made, because I believe that to be true to sport you really have to try to be the best that you can, and I'm happy with the decisions that were made".
Hubbard said it was likely she'd ruptured a ligament and sustained "some fairly significant tissue damage".

In Hubbard's absence, Stowers won the gold with a total of 253, followed by Charisma Amoe-Tarrant of Nauru (243) and Emily Campbell of England (242). "But there's no indication at all today that they were anything other than absolutely fantastic, a real credit to the Australian people and also the broader sporting community".
An emotional Stowers declined to speak directly to reporters but a Samoa team official said the lifter felt "shocked and so happy" that Hubbard had withdrawn.
A Kiwi TV commentator described as soon being a "striking twist" later Hubbard had seemed well on her way to the gold medal.
