Environment - Non Weather Related; Procedure
Smooth at FL330 with seat belt sign off. Momentary moderate turbulence 5 seconds in duration. Rolled 15 degrees; autopilot stayed on. Immediately turned on seat belt sign and started to make PA 'Flight Attendants (FA) be seated immediately'. But the jolt was over and back to smooth air. I called Lead FA; and asked if all was ok. She stated yes; and it stayed smooth until landing. After deplaning; FA came forward and advised me she was injured and fell during the turbulence encounter. I called [a pilot manager] and [flight attendant manager] and we all 4 agreed that she was OK to work return flight. She stated her left wrist and right hip were sore. She stated that she wanted to continue to work and was physically able to do so. I suspect it was perpendicular wake turbulence encounter due to the sudden onset and passing. I saw no crossing traffic and it was VFR smooth before and after. No time to make PA. It was over in 5 seconds and smooth again.
