Wall, 28, is expected to finalize a timetable for the procedure in the coming days, sources said. Recovery could sideline the point guard for six months.
Doctors determined the procedure is necessary for Wall to remedy an issue that has bothered him for more than a year. Wall met with specialist Dr. Robert Anderson on Saturday, who recommended the surgery.
Wall was trying to play through the injury, but it was getting worse, sources said, and opting to have the surgery now should allow him to return healthy for the start of next season.
The Washington Post first reported that surgery could be necessary.
Wall, who is averaging 20.7 points and 8.7 assists per game, has been able to manage the pain and looked like his All-Star self in some games this season, such as on Dec. 16 in Los Angeles, when he scored 40 points with 14 assists against the Lakers.
But other times, the pain and swelling made it hard to move, such as on Dec. 8, when the Cavaliers held him to 1 point. He then missed Washington’s next game two days later in Indiana.
Tomas Satoransky started in Wall’s place against the Bulls.
