The former Blackburn striker, 35, has not featured for Brian McDermott's Royals since the 1-0 defeat at Southampton on 8 December.
He Tweeted: "Rehabilitation has not been successful. [It] seems at this point surgery is our only option meaning my season is over.
"Everything that could have been done has been done."
Roberts has made nine starts for Reading this season and his only goal came in the 7-5 Capital One Cup defeat by Arsenal.
He joined the Royals for an undisclosed fee from Blackburn in January 2012.
