THE LOW DOWN: Rafael Nadal's knee troubles, seeks laser doctor to the stars

All the talk about Rafael Nadal at the US Open hasn't been about his trademark aggressive baseline playing. This week the World No. 2 has been facing questions about his balky knees and the tendinitis plaguing them. Apparently he's been visiting Italian surgeon Pier Francesco Parra, who has used his laser treatments to cure what ails dozens of tennis stars, soccer players and Olympic skiing champion Alberto Tomba.

The Spaniard initially visited Dr. Parra on after Monday's practice session and then today. "It's like doing arthroscopic surgery, but without cutting the skin," Parra said. "And it takes 23 seconds."
