The midfielder sustained the problem while on international duty with France recently.
Despite reports claiming that he could return before Christmas, Pardew does not expect to have the 26-year-old available until January at the earliest.
"Cabaye might possibly have to have a little surgery on that groin. You have seasons when you lose players and you have to be able to cope with it," Pardew told the Shields Gazette.
"If I had everybody available then losing Cabaye would not be such a blow. At the minute we cannot afford to lose anybody."
Cabaye has made 10 appearances for the Magpies this season, scoring two goals.
