Wroten was hurt in a game last week against New Orleans and was sent to a knee specialist in California. The Sixers announced before Friday's game against Toronto that Wroten would need surgery. They did not say when the surgery would take place.
Wroten is averaging 16.9 points and 5.2 points in 30 games this season. He is shooting 40.3 percent from the field. He was the 25th overall pick in the 2012 draft by Memphis.
