"I think unless something goes really well, I wouldn't get there," Lin was quoted by the Associated Press as saying before the Knicks played the Chicago Bulls on Sunday.
"It depends on how far and how long it goes.
"But obviously I want to get to 100 percent and then come back, hopefully see what I can do. By then it'll be a different team identity, chemistry, so it gets tricky, too. Yeah, I'm doing everything, we're doing everything we can to get back as soon as possible."
On Monday, Lin went under the knife to repair torn cartilage in his left knee and is expected to be out for around six weeks. The NBA playoffs are set to begin on April 28 2012.
The Knicks remain in the hunt for the playoffs - they lead the Milwaukee Bucks by one game for the eighth spot - following a 100-99 win over the Chicago Bulls.
Carmelo Anthony's three-pointer with 8.3 seconds left took him to a season-high 43 points and secured the win for New York.
Derrick Rose returned to the Bulls line-up after missing 12 games but shot only eight-of-26 and missed key free throws down the stretch in the loss to the Knicks.
