Federer Announces Right Knee Procedure, To Return In 2021

The Swiss previously underwent surgery on his right knee in February

Roger Federer announced on Wednesday that he recently underwent a "quick arthroscopic procedure" on his right knee, and he will not play until 2021.

“A few weeks ago, having experienced a setback during my initial rehabilitation, I had to have an additional quick arthroscopic procedure on my right knee,” Federer tweeted. “Now, much like I did leading up to the 2017 season, I plan to take the necessary time to be 100 per cent ready to play at my highest level. I will be missing my fans and the tour dearly. But, I will look forward to seeing everyone back on tour at the start of the 2021 season.”

Federer underwent surgery on the same knee in February. The Swiss' initial plan following that surgery was to return during the grass-court season.

The 38-year-old's lone tournament of 2020 came at the Australian Open, where he reached the semi-finals. Eventual champion Novak Djokovic defeated him in straight sets.
