He came back from that on New Year's Day and has averaged 14.2 points in 29 games off the bench.
Smith, who scored a season-high 36 points Thursday but missed the potential winning shot, made four 3-pointers and Novak was 5 of 10 behind the arc.
Raymond Felton finished with 15 points for the Knicks.
Utah's last three losses had come by a combined five points, falling 89-88 on Friday in Chicago on Marco Belinelli's late 3-pointer. But the Jazz were out of this one early in their seventh loss in eight games.
"Obviously there's not anybody in here that's not frustrated at this point from players to coaching staff to the trainers. Everybody is frustrated," said Utah's Marvin Williams, who had X-rays on his left hand that revealed just a bruise. "It's a crucial time of the season. We're in a serious spot right now and each game we've got to come out and play with a sense of urgency."
The Knicks led by two before Novak and Felton made 3-pointers in a 10-0 burst that made it 41-29. Al Jefferson made a hook shot, but Novak answered with consecutive 3-pointers before Pablo Prigioni sank a pair of free throws to make it 51-33 with 1:46 remaining in the half. The lead peaked at 55-36 on Tyson Chandler's dunk and the Knicks were up by 17 at the break.
It ballooned to 75-45 on a pair of free throws by Iman Shumpert with 4:15 left in the third and would eventually reach 32.
Chris Copeland scored 12 points in just seven minutes and Kenyon Martin, now likely to have a bigger role in the rotation, scored 10 as the Knicks' reserves, who came in third in the NBA with 40.3 points per game, totaled 75.
"It's unfortunate Amare's going down, (I've) got to benefit from something like that," Martin said. "I'm going to take advantage of it and help the team win."
