Last fall's knee injury continues to linger but Andy Roddick is pronouncing himself ready for the Australian summer.

"I'm definitely not coming in under-practiced, thati's for sure," Roddick told reporters in Brisbane. "I probably played more tennis this December than I have in the last couple of years."

Describing the state of his knee, Roddick said, "I don't know if it will be perfect for a while, but it's close.

"It's a matter of getting a range of motion back... It's nothing to do with power or the way it feels when I'm running."
