CAROL COSTELLO, CNN ANCHOR: This just in to the CNN news room. Queen Elizabeth has left a London hospital after having surgery on her right knee. She flew through that surgery just fine. She had surgery on her right knee, I think to remove some stuff floating around in there. She's 76 years old. The operation took about 45 minutes. She's in that Range Rover, we think, leaving the hospital now. She's off to Sondringham, where she will recover over the next two weeks and then she will resume a limited program of engagements. Queen Elizabeth out of the hospital this morning.
