Bledsoe was hurt on Saturday in a loss to the Philadelphia 76ers, an embarrassing defeat to a team that had won just one other game this season.
The Suns said the operation will be performed on Tuesday, and there is no timetable yet for Bledsoe's return.
It's a tough blow for the Suns, with Bledsoe averaging 20.4 points and 6.1 assists in 31 games this season.
The news came on the same day that ESPN reported Suns coach Jeff Hornacek's job could be in danger.
Hornacek described Saturday's loss to the lowly 76ers as "a low point" for a team in the midst of a 5-15 stretch.
"Now the confidence is lacking," said Hornacek, whose team was expected to contend after the arrival of Brandon Knight last February and the offseason addition of Tyson Chandler.
