A source close to Gaborik said the surgery for the injury -- suffered in Game 3 or 4 of the first round of the playoffs against Ottawa -- would sideline him for up to six months.
Gaborik will have the procedure at the NYU Langone Medical Center's Hospital for Joint Diseases in Manhattan, the Rangers said. It will be performed by Dr. Andrew Feldman and Dr. Anthony Maddalo.
The 30-year-old forward was criticized for his inconsistent production throughout the playoffs.
He was limited to one goal in the team's conference final series against the New Jersey Devils after recording 41 goals and
35 assists during the regular season.
"I don't want to make excuses but it was there," Gaborik said on a conference call with reporters. "I would say (the injury) affected me."
"It's frustrating. It is what it is," Gaborik added. "I just have to focus on getting back healthy and being ready to go.
"I know I could've played better. I don't think it affected me that much. It was just weak. During the game, the adrenaline kicks in and everything goes to the side. Shooting, my shot wasn't there, obviously, but I don't want to make excuses. I tried to put it aside and focus on playing. It wasn't just me -- a lot of guys were banged up. You just try not to think about it and go out there and do your best."
