Mark Philippoussis could be ready to play again in six weeks following successful surgery on his right knee.
Philippoussis injured his knee while reaching for a backhand
The 30-year-old's career looked in doubt when he tore the lateral meniscus in his knee during the Hopman Cup in Perth on Tuesday.
But Dr Merv Cross described the operation in Sydney on Thursday as "straightforward".
"I expect that after six to eight weeks he'll be running around and able to play competitively again," said Cross.
He told the Sydney Morning Herald: "(The operation) was very straightforward.
"He had quite a large tear in the meniscus, and about 30% of it had folded back into the joint, which made it very painful for Mark."
Philippoussis has had three previous knee operations but it was the first time the 2003 Wimbledon finalist had undergone surgery to his right knee.
Speaking before the surgery, Philippoussis said: "It is disappointing, but what can you do?
"This is another minor setback and something I am going to deal with. It is the only thing I can do, it is the only thing I want to do, it's as simple as that.
"People used to be thinking about retiring at 30, but Andre Agassiz has shown that if you stay physically strong you can keep going."
