Anthony Anderson Says He’s Good After Fluid Drained From Knee

Anthony Anderson says he feels like he can tap dance after getting 140cc of fluid drained from his knee … and he thinks doctors may have misdiagnosed him with the “disease of kings” — AKA gout.

We got Anthony at LAX on Friday and our photog asked him about his scary knee issue … which landed him in the ER after a bunch of nasty swelling.

Anthony says he’s been told he may have gout and needs to cut back on red meat and alcohol … but it sounds like he’s not buying it, and thinks he just has arthritis instead.

After all, the comedian jokes he needs his red meat … and he can move his knee around just fine after his hospital visit … showing off his flexibility for our camera.

Anthony’s in good spirits here — safe to say his sense of humor hasn’t been drained.
