New York, NY (My Sportsbook) - New York Knicks power forward Antonio McDyess underwent successful surgery on Wednesday to repair a fractured kneecap, which he suffered in Saturday's preseason game against Phoenix.

Since the weekend, McDyess sought second and third opinions which confirmed the original diagnosis of a fracture. McDyess is expected to miss the entire season.

"Although we expect the full rehabilitation process to keep him out the entire season, this is not a career-threatening injury," said Dr. Norman Scott, who performed the surgery. "He will be able to walk on crutches and put full weight on (the knee) later this week. We expect him to have a full recovery and be 100 percent by the start of next season."

McDyess injured his left knee late in the fourth quarter of his team's 94-87 loss to the Suns. McDyess dunked a miss by his teammate Howard Eisley, and fell to the ground clutching his knee in pain.

McDyess missed all but 10 games of last season after injuring the same knee with Denver. The Knicks acquired McDyess from the Nuggets in a draft-day trade.

After scoring 23 points and grabbing 15 rebounds, MyDyess was able to limp off the court on his own power before heading to the locker room.

The Knicks are also without Latrell Sprewell, who will be sidelined six-to- eight weeks with a broken hand.

McDyess, who averaged 20.8 points and 12.1 rebounds two years ago, had surgery on his left knee on October 12 of last season and was placed on the injured list. He came back on March 1, but was in and out of the lineup the rest of the way.
