New York Knicks all star Carmelo Anthony has decided to end his season after having surgery on his left knee, according to ESPN.

Anthony’s procedure included a left knee patella tendon debridement and repair, which will keep him off the court for four to six months.

“What we’re finding out from the medical is …, it could be four to six months,” Knicks president Phil Jackson. “We can’t put it at a timetable until after the surgery. But that’s what they’re saying. They say it can be anywhere between four to six months for Carmelo to be back on the floor.”

This is not the first time Anthony has had trouble with his left knee.  In 2011, Anthony had an arthroscopic procedure on his left knee.

Anthony played 30 minutes in the NBA All Star game in New York on Feb. 15, but only finished with 14 points on 6-of-20 shooting.

Anthony currently leads the Knicks in points per game with 24.2 and rebounds per game with 6.6.

The Knicks have the worst record in the NBA at 10-43.  The Knicks have not won a game this season without Anthony, who already missed 13 games this season.
