Ireland said that at the time, she was performing with a leg that was "twisted, torn, [and] needing surgical repair."
"During the show...knew I would need knee surgery...but why talk about it while people were voting?" she reiterated on her Twitter account.
Ireland added she plans to have knee surgery after she performs during Dancing with the Stars ninth-season finale on November 24.
"Will dance, dance, dance...whatever---no sympathy votes 2 worry about anymore," she posted.
