The Knicks scored the final 18 points of their game against the Hornets on Friday night.
New York won 113-96 with Al Harrington scoring 28 points.
"Our defense was horrible," New Orleans guard Chris Paul said. "We've had a few games where our defense was good, but not tonight, and it was obvious we couldn't buy a shot."
The win was the Knicks' fourth straight. They hadn't won four consecutive games since Jan. 2-13, 2006.
New York trailed 96-95 with less than five minutes left.
"Everybody hit big shots, one after another," New York coach Mike D'Antoni said. "We were moving the ball really well. We're just playing really well right now."
