Narrative:

Landing at lax; runway 24R. We had a firm landing. I felt no need to enter anything in the aircraft log. No masks dropped. It was just a firm touchdown. Entered wake turbulence at about 40 ft AGL. Found out from my first officer who was greeting passengers after flight that a male passenger complained of an injury due to landing. It's an everyday occurrence. Talk and plan.
