Narrative:

Climbing through FL350 enroute to atl; we encountered suspected wake turbulence off a B747 10 miles ahead of us. We had momentary loss of control of the aircraft; banking in excess of 45 degrees to the right. Flight attendants were already taking drink orders and in the aisle when the encounter happened.through the upset recovery process; the flight attendants laid on the floor and one of the flight attendants injured her knee in doing so. No diversion was needed and we continued onto atl.we never saw that aircraft on TCAS until after the fact. And at 10 miles; we would have never thought of wake turbulence. But that being said; we might have the flight attendants stay seated until TOC (top of climb) when feasible.
