Germany and Real Madrid midfielder Sami Khedira has had successful surgery on torn knee ligaments and he may be available for the World Cup, according to Germany team doctor Hans-Wilhelm Mueller- Wohlfahrt.
.
"The operation went well," Mueller-Wohlfahrt said on the German soccer federation website (www.dfb.de).
.
"Now we hope that Sami will be back to fitness for the World Cup in Brazil (starting in June)," he added.
.
Real confirmed the success of the surgery, which took place under the supervision of club doctors at a clinic in Augsburg, Germany on Saturday.
.
"Over the next three weeks the player will follow a specific recovery plan so the injured ligaments heal correctly," the Spanish club said on their website (www.realmadrid.com).
.
Khedira is expected to be out for around six months after damaging the knee in Friday's 1-1 draw with Italy.
.
Germany coach Joachim Loew said it was a "bitter setback" but that he was optimistic he would recover in time to feature at the finals in Brazil.
.
Khedira's enforced absence is a blow for Real, who have only just got his midfield partner Xabi Alonso back after a five-month injury layoff.
.
Alonso suffered a bruised ankle in Spain's 2-1 win in a friendly against Equatorial Guinea on Saturday but coach Vicente del Bosque said it was nothing serious.
