“(Nadal) has a problem typical in tennis with a back joint, he had it at the Australian Open, and we have decided to treat it with stem cells,” Ruiz-Cotorro said.He said that stem cells were recently extracted from Nadal for a cultivation process to “produce the necessary quantities.”“When we have them we will put them in the point of pain,” he said, with the goal of “regenerating cartilage, in the midterm, and producing an anti-inflammatory effect.”
Nadal’s coach and uncle, Toni Nadal, told Marca.com the 14-time Grand Slam winner will undergo the treatments over a five-week span and hopes to be back in training by December.
Even with the back injury and an injured wrist, Nadal still won four titles last season, including his record ninth French Open. He’s currently the No. 3-ranked player in the world.
