The 27-year-old missed the second half of last season after tearing his cruciate ligament.
But with QPR back in the Premier League following promotion through the Championship play-offs, their longest-serving player has been handed fresh terms until July 2015.
"It's nice to sign the new deal," he told the club's official website. "It took a little bit of time, but I am so happy everything is now sorted.
"It's been quite an amazing journey so far - relegation, promotions and plenty more - but it's been a beautiful experience.
"I hope the next chapter is the most epic yet.
"The Premier League is where every player wants to play and I am no different.
"We all know that the Premier League will be very difficult, with so many great teams, but we are looking forward to the challenge ahead."
