(CNN) Tiger Woods has revealed he underwent knee surgery last week and says he hopes to return to golf in October.

The Masters champion announced he had arthroscopic surgery to repair minor cartilage damage in his left knee.

The 43-year-old said he will return at the PGA Tour's new event -- the Zozo Championship -- in Japan from 24-27 October.

"I'm walking now and hope to resume practice in the next few weeks," the 15-time major winner said on Twitter. "I look forward to traveling and playing in Japan in October.''

Woods has had a number of procedures on his left knee over the course of his career, and in recent years has undergone four back operations including spinal fusion surgery in 2017.
