It's really not necessary to know the back story in order to enjoy the game. Metal Gear Solid games can all be played on their own. There will be many references you won't understand, yes, but the gist of what's going on will always be independent of the other games.
The original MGS has a lot of references to the old Metal Gear games, none of which I've played to this day. But I fully enjoyed the game back then and still do now, it's not something that prevents a comprehension of the storyline of the particular MGS game you're playing.
