The Knicks, who last won Jan. 4 against the Los Angeles Lakers at Staples Center, broke their previous record of 16 straight defeats set in 2014-15 when they finished with a franchise-low 17 wins.
This season's Knicks team is now 10-46 -- the worst record in the NBA -- with 26 games to play.
The franchise's longest overall losing streak was over the course of two seasons, from March to November 1985.
Monday's 17th straight loss also tied the Knicks with the New York Mets -- who lost 17 in a row in their expansion season in 1962 -- for the longest single-season losing streak by any New York-area team in the past 100 years.
As one of the three teams with the worst record in the NBA, the Knicks right now have a 14 percent chance of getting the first overall pick in the NBA draft.
Their next chance to end this current skid comes Wednesday against the Philadelphia 76ers.
