Roger Federer will stay out of the court up to a month after undergoing arthroscopic knee surgery in Switzerland to repair a torn meniscus, his agent Tony Godsick said.
The 17-times grand slam champion suffered the injury the day after his Australian Open run ended in the semi-finals last week.
Federer has withdrawn from the ABN Amro World Tennis Tournament in Rotterdam, which runs from 8-21 February, and the Dubai Duty Free Tennis Championships in Dubai (22-27 February).
