The 30-year-old Germany international, who played a key role in the Foxes' successful Barclays Premier League survival charge at the end of the campaign, has signed a three-year deal after the club agreed an undisclosed fee with Stoke.
He becomes manager Nigel Pearson's second summer signing following the arrival of Austria defender Christian Fuchs from Schalke earlier this month.
