Their effort sent the spiraling Celtics to their fifth straight loss, while the Knicks increased their Atlantic Division lead over the third-place Celtics to seven games.
New York took a 10-point lead midway through the fourth quarter, but Rajon Rondo tossed Boston on his back and brought the team back to within two. Then New York's defense came up with two enormous stops to halt the comeback bid.
Carmelo Anthony showed little to no emotion as it related to Kevin Garnett and their prior incident on his way to a game-high 28 points. Amar'e Stoudemire hopped off the bench to supply 15 points and nine rebounds.
Rondo finished with yet another triple-double, with 23 points, 11 assists and 10 rebounds, but it went for naught in the loss. Paul Pierce tallied 22 points as well.
The win moves New York to 26-14, and they are just 1.5 games behind the Miami Heat for the East's No. 1 seed. Boston's loss continues their struggles, as they are now just 20-22, clinging tight to the No. 8 seed.
