Like every other season, Andrew Bynum has struggled mightily with his knees this year, having not appeared in a game yet for the 76ers because of them. There's still no real timetable for his return, but he still intends to play this season.

And in an effort to aid that return, Bynum got a planned injection in both knees to help take a little of the stress out of them. Via CSN Philly:

The Synvisc injections, which Bynum received in both knees, are common for basketball players readying to pick up their action on the court. A Sixers' spokesman said the appointment with Dr. (David) Altchek was scheduled previously and is not a setback.

Again, key phrase: "not a setback." Still, any time you're talking about a needle going into Bynum's knees, things get a little dicey. Bynum had similar injections in his knees before the season, but his setback then was unrelated. He also had the injections at All-Star Weekend last season in Orlando, and played in the game just a few days later.

Bynum is currently practicing, a positive sign for his return. But he's still being cautious because he says he has to protect himself from himself.
