The Knicks are ready to write a new book: “How the West was Lost.’’

Carmelo Anthony’s return was a complete disaster and the Knicks were a complete mess last night as they began their daunting, five-game West Coast trip with a disgraceful 92-63 loss to the Warriors at The Oracle. It was a season low for points for the Knicks, whose previous low was 76, and they shot an embarrassing 27.4 percent (20 of 73).

Anthony, after missing three straight games with fluid in his right knee, had no fluidity to his game, pop in his legs or rhythm to his jumper, stinking out the Bay Area with a 4-of-15 brickfest.

“It was real sore,” Anthony said. “I tried to get through it and figure it out. I didn’t know how it would respond. It was agitation. I felt it out there.”

In 34 minutes, Anthony finished with 14 points and 10 rebounds but also spent the night out of position on defense.

“He was a little sluggish. We expected that,” coach Mike Woodson said. “We can’t use that as an excuse. We still have enough bodies without him.

“We had nothing going on offensively. We played one quarter. After the first quarter, that was it.”

It’s not an ideal time for Anthony to be in a funk. Tomorrow, he makes his first return to Denver since forcing a trade to the Knicks during the 2010-11 season.

Anthony played 30 minutes before being benched with 2:14 left in the third quarter and the Knicks trailing by 27 points, 74-47. Surprisingly, he returned with 9:16 left and a hit a 3-pointer before he was taken out for good with 5:25 left, down 24.
