Analysis of Rafael Nadal's Knee Injury - Computer Animation from NYTimes

Rafael Nadal missed seven months last year with a knee injury. Nadal, an 11-time Grand Slam champion, returned to the tour at a small clay-court event in Vina del Mar, Chile, in February after recovering from a partially torn patella tendon and inflammation in his left knee. That knee will face its toughest test when he plays in the French Open, his first Grand Slam event since his return.



The 26-year-old Spaniard is favored to win and become the only player with eight French Open titles, even though he said his knee is still “not 100 percent.” Although he can practice less than an hour a day, he’s made the final in each of the eight tournaments he’s played since he returned to the men’s tennis circuit in February.
