The Spanish club said earlier on their website that Kaka had
suspected meniscus damage and might need surgery.
He was examined by knee and sports injury specialist Marc
Martens in Belgium and Martens's assistant at the clinic in Antwerp told
Reuters that a half-hour arthroscopic operation was carried out on Thursday
morning.
"It went well," the assistant said. "The
typical recovery period for this is three to four months." Brazilian Kaka,
who has been plagued by injuries over the past year but recovered to play in
the World Cup in South Africa, had left Real's pre-season training camp in California
to fly to Belgium.
"He's a very popular player among his team mates and
also a very good player but we want him at 100 percent so that he is
happy," coach Jose Mourinho told a news conference in San Francisco after
Real beat Club America 3-2 in a friendly.
"If we have to lose him for a while it won't be a
drama," the Portuguese added. "We have other players and that's
that." Kaka, 28, joined Real from AC Milan in 2009 for a fee of around 65
million euros ($85.3 million). He made 25 league appearances last season,
scoring eight goals.
Real play a friendly against Major League Soccer (MLS) club
LA Galaxy on Saturday in Los Angeles.
