Stu Shiffman underwent surgery to repair his broken kneecap on June 25. He is now breathing well enough and his other vital signs have stabilized to a degree that doctors felt confident in giving him the general anesthetic required for the operation.

Stu suffered the knee injury on June 15 when he managed to get out of bed the second night after being hospitalized for a stroke. (See additional details at CaringBridge and Facebook.)
