Los Angeles: Actor Zac Efron had to undergo a surgery after he tore his Anterior Cruciate Ligament (ACL) on a recent ski trip.

The actor shared the news on Twitter with a photograph in which he is sitting in a wheelchair with his left knee in a brace. 

In the picture, he sticks out his tongue and flashes the "hang loose" sign.

"I tore my ACL... But all is good. I opted for surgery so I can come back stronger than ever. Thank you to Dr Kvitne and his team at Kerlan-Jobe Surgery Center. I'll keep you updated as I heal and progress. Thanks for all the love and positivity," Efron, 31, tweeted. 

The actor will next be seen in "Extremely Wicked, Shockingly Evil, and Vile", a biographical crime thriller on serial killer Ted Bundy.
