“It almost feels like going home,” joked Plushenko, who at the age of 30, and days before becoming a father for the second time, combines a Zen-like detachment with a sense of invincibility that would make any teenager proud.
“It was a thermal treatment of a disk hernia,” he explained about the surgery. “They make a cut, enter a catheter, and can follow the process on a monitor. Surgeons sear the hernia with a special liquid under general anesthesia. You are not allowed do anything for ten days. I was back on the ice in seven.”
“After the surgery, the doctors told me to stay off ice for a month,” he added. “However, it was not for me. As usual, I had to jump the gun. I felt that need to run fast in order to defend my position. I had the National Championships coming up, so, not only did I start to train too early, but I started to train too intensely.”
As a result, complications arose which required another medical intervention, this time closer to home.
“I got an injection, a block, in St. Petersburg at a presidential clinic,” he said.
Unsurprisingly, his physical condition plummeted.
“I am a grown up man, but I cried in practices because I was not able to do anything,” revealed the three-time World champion. “I was not able to land a triple loop, triple Salchow, or triple Lutz. I had to start from the scratch. All the progress I had achieved this summer … it was gone. I felt like giving up.”

The next stop for the ten-time National Champion is another visit to a doctor’s office.
“This was the most important National title in my career,” he said. “The circumstances were very difficult. I wanted to withdraw. Or, more accurately, to withdraw would have been a right thing to do at the time. So, now I will take a short break and I will have another injection in St. Petersburg and let the doctors work their magic on me.”
“Then I will prepare for the Europeans,” he continued. “The rivals will be strong, so I have to bring back two quads and a quad-triple combination. I think my muscles are up to the task, but everything depends on my back now.” "
