WASHINGTON – Sixers general manager Tony DiLeo said surgery for Andrew Bynum is “certainly an option,” though the organization is trying to determine the appropriate next step for their injured center and his balky knees.

And, for those wondering, Bynum is still Plan A for the Sixers this season and beyond, according to DiLeo.

Bynum – who has missed the entire season – practiced with the Sixers Feb. 22, with that 5-on-5 scrimmage serving as his first on-court workout with his teammates since being traded to Philly. Bynum has been suffering from swelling in his right knee ever since.

Friday, Bynum said there are no surgical procedures to fix the cartilage issue he's battling in both his left and right knees. However, DiLeo did not dismiss the notion that going under the knife was a possibility for Bynum.

“(Bynum) probably knows as much as anyone. He's seen all the doctors,” DiLeo said Sunday, before the Sixers tipped off with the Washington Wizards.

“Now he has to make a decision, the doctors have to make a (decision) – what’s the next, best step? Is it continuing to rehab? Or go in and do arthroscopic (surgery)? Or is there some other alternative? That’s where we’re at right now.”
