Basel, Switzerland: Seventeen-time Grand Slam winner Roger Federer underwent "successful" surgery on his knee Wednesday and will be ruled out of action for one month, his agent said.
Federer underwent the surgery to repair a torn meniscus sustained the day after his semi-final match at the Australian Open, according to Tony Godsick.
As a result of the surgery, Federer will now miss the ATP tournaments in Rotterdam and Dubai this month.
"I am so disappointed to have to miss Rotterdam and Dubai as they are two of my favourite tournaments on the ATP World Tour," Federer said.
"While this is an unfortunate setback, I feel grateful that up until now I have remained mostly healthy throughout my career. My doctors have assured me that the surgery was a success and with proper rehabilitation, I will be able to return to the Tour soon."
Federer informed his fans of the news on Facebook as well.
The 34-year-old Swiss great suffered a four-set defeat by eventual winner Novak Djokovic in the Australian Open semi-finals, going down 6-1, 6-2, 3-6, 6-3, in his eighth loss to the Serb in their last 10 Grand Slam meetings.
Federer hasn't beaten the runaway world number one at a major since the Wimbledon semi-finals in 2012, when he last won a Grand Slam title.
