The 22-year-old was understood to be carrying the slight problem through the last few months and he will now go under the knife and miss the last part of Tottenham's Premier League season.
"The operation will rule the midfielder out of our final fixture of the season at Liverpool on Sunday," read a statement from the club.
The news comes as another blow to manager Harry Redknapp who is already without Wilson Palacios for the rest of the campaign due to a family bereavement, while fellow midfielder Jermaine Jenas came off during the Manchester City win at the weekend through illness.
Redknapp is also monitoring the fitness of centre-back Jonathan Woodgate, who was thought to have injured his groin against City.
The London based club need to win against Liverpool and will be hoping Fulham lose their final game of the season if they are to qualify for the Europa League.
"Fulham look nailed on. But it is possible," Redknapp said.
Tottenham have made an incredible comeback under the guidance of Redknapp this season having made the worst start to a campaign in the club's history.
Admitting even he had been shocked by the side's progress, Redknapp said: "If, when I arrived, you had said we would still be in with a chance going into Europe in last game, I wouldn't have believed it. Let's be truthful, I would have taken fourth from bottom when I arrived."
