Nick Kyrgios is ready to do "everything I can do get back to my best" after undergoing knee surgery.

Last year's Wimbledon runner-up was left "devastated" when he had to withdraw from the Australian Open.

Kyrgios was ruled out of his home grand slam after an MRI scan on his knee revealed a cyst as a result of a small lateral meniscus tear.

The world number 21 on Monday revealed he had gone under the knife and is looking forward to starting out on the road to recovery.

He posted on Instagram: "Surgery complete. I'll be doing everything I can do get back to my best. To the real ones checking in and sending the vibes…. I love you."

Kyrgios won the seventh ATP Tour singles title of his career in Washington last August and claimed the Australian Open men's doubles title with Thanasi Kokkinakis in his homeland 12 months ago.

The 27-year-old was beaten by Novak Djokovic in his maiden major singles final at the All England Club last July.
