Rafael Nadal’s doctor, Angel Ruiz-Cotorro of the Spanish Tennis Federation who has treated the 11-time Grand Slam champion since he was 14, tells Mundo Deportivo
that Nadal’s injury "is annoying and painful, but not significant."
Ruiz-Cotorro said that Nadal suffers from the disease Hoffa's syndrome, which is "fat inflammation" behind the patellar tendon and is part of the tendonitis suffered by Nadal. Hoffa's syndrome occurs when the fat pad becomes pinched between the distal thigh bone and the kneecap.
"He's doing well. Next week it will be tested and if the result is positive we will continue with the same treatment," said Cotorro, who added that Nadal is trying to deflate the tissue in his knee during his rehabilitation process via physical therapy, electrodes, laser and deep thermotherapy.
According to medical web sites, if the type of treatment Nadal is using now does not work then surgery may be advised. This may involve the complete or partial removal of the fat pad itself.
Nadal told Reuters TV
that he wants to make a full recovery from his knee injury before returning to the tour, but is aiming to play Spain’s Davis Cup tie against the United States the weekend after the U.S. Open.
"The important thing is to recover well and come back when my knee is 100 percent perfect. We'll see if I will be ready for Gijon, for the Davis Cup. My goal, my dream is to be there if the captain has confidence in me, but it always depends on the captain and the knee."
Nadal also revealed that he first started feeling pain around February before Indian Wells.
"I played these months with some problems, like in Miami [where he retired against Andy Murray], but normally I had the control of the pain, of the injury. But after Roland Garros the injury got worse and it was impossible to continue competing, and of course the important thing today is to recover as fast as possible after not arriving in perfect conditions in Wimbledon."
