The Hawks say the surgery was performed on Tuesday at the Emory Orthopaedics & Spine Center in Atlanta.
Bembry suffered the injury in the season-opening win at Dallas last Wednesday.
Bembry averaged 2.7 points in 38 games, including one start, as a rookie last season and was targeted for a bigger role on the rebuilding Hawks. He scored six points in 18 minutes off the bench before suffering the injury against the Mavericks.
