Kaka out for 4 months after knee surgery

Real Madrid midfielder Kaka is facing a spell of up to four months on the sidelines after undergoing knee surgery, the Spanish club hs confirmed. The Brazil star had been with Jose Mourinho's side on their pre-season tour of the United States but left their base in Los Angeles to travel to see a knee specialist in Belgium. Kaka had a disappointing World Cup with his country, as they were knocked out in the quarterfinal by Netherlands, and was troubled by a groin injury during the tournament in South Africa. He joined Real Madrid from Italian giants AC Milan in June 2009 for a then world record fee of $88 million but only made 22 appearances as his new club finished second to champions Barcelona. The half hour operation in Antwerp on Thursday morning was hailed as a success but Real fans may have to wait until December to see the 28-year-old back in action. A statement on the club's official website read: The operation performed on the left knee of Real Madrid C.F.'s Ricardo Izecson Dos Santos Leite 'Kaka' by Dr. Marc Martens at Antwerp's AZ Monica Hospital was a success. The arthroscopic surgery confirmed an injury to the left meniscus with minimal inflammation of the cartilage. The player is expected to miss three to four months.
