Former World No. 1 Roger Federer admitted that opting to have another knee surgery was a difficult decision, but felt it was the right thing to do. Federer, who underwent two knee surgeries last year, returned last March. After losing in the Wimbledon quarterfinals, Federer withdrew from the Tokyo Olympics, before announcing a third knee surgery in August.
"It was a difficult process to make that decision, just because I already had a couple of knee surgeries last year," Federer told former American world number one Jim Courier in an interview at the Laver Cup on Saturday.
"I was really unhappy with how things were at Wimbledon. I was nowhere near where I wanted to be to play at the highest, highest level. But I did the best I could and in the end, at some point, too much is too much. Now I have to go step by step."
Federer, who turned 40 last month, doesn't want to rush into anything as he is taking his time and trusting the process. "First I have to walk correctly again, run correctly and then do the side steps and all the agility work and then finally I have to get back on the tennis court," he said.
"But it will take me a few more months and then we will see how things are at some point next year."
Federer was defeated in straight sets by Hurkacz
Following his quarter-final exit at Wimbledon this year, Roger Federer spoke to Jonathan Heaf of the GQ Magazine about a number of topics, including his campaign at SW19 and how he has modified his training regimen with age.
"Obviously, it's always hard leaving a court after losing at Wimbledon earlier than a final… When you reach a final, there's a trophy ceremony, there's more to it, but when you lose earlier, well, you pack your stuff and you go and, at that point, the stage is your winning opponent’s, in my mind, not yours.
So that was important for me to give that one to Hubert [Hurkacz], obviously, as quickly as possible," Federer said. The Swiss nevertheless expressed satisfaction over his run to the quarterfinals at Wimbledon for an 18th time.
Federer was quick to point out that many players had never made a single last-eight appearance at SW19, and that it was important not to take any result for granted. "But at the end of the day, I made the quarters – I played Wimbledon," Federer remarked.
"You can never take that sort of thing for granted: remember, other guys never had a quarterfinal in their life at Wimbledon and I've had so many that I think I have got to have a little perspective and see that actually, overall, it was a really good tournament for me."
