The surgeon who repaired the injuries to Petra Kvitova's left hand after a knife attack believes the two-time Wimbledon could be back on the practice court in no fewer than six months.

Surgeon Radek Kebrle said that the operation on Petra's left hand went very well, with no complications," Kvitova's publicist said in a statement.

"Petra will be on bed rest for 14 days, she will begin slow rehabilitation at around 6-8 weeks post operation. If that rehabilitation process goes well, Petra should be able to grip a racket for the first time (but not play tennis) at three months. The best-case scenario is that Petra will be able to return to the tennis court after six months.

"It is too soon to specify when precisely she can return to competition, but Petra is ready to do everything she can to get back competing at the highest level. Petra is happy with how the operation went and is in good spirits."
