Kristaps Porzingis had successful surgery on Tuesday to repair the torn ACL in his left knee, the Knicks announced.
Recovery time for a torn ACL is usually between eight and 12 months, and Porzingis is expected to be out for at least 10 months, reports Ian Begley of ESPN.
The 22-year-old Porzingis was averaging 22.9 points through 47 games for the Knicks in his third NBA season, and was set to play in his first All-Star game before getting injured.
Porzingis suffered the injury during last Tuesday night's game against the Bucks, suffering the injury when he came down from a dunk.
He slapped the court after landing, clutched his knee, and was eventually helped off the court by other members of the Knicks before heading to the Hospital for Special Surgery to undergo an MRI that confirmed the injury.
