@bobjonkman @trouble @ascentale @PamelaSchure @bikenite I lowered my saddle more than 1cm not long after I got the touring bike (wow, seven years ago now), and that helped a lot. Haven't had pain while riding since then (as opposed to walking).
The knees and I, we have a history and I've had some very good care. Age and weight are factors here as well. I'm taking it easy and if the pain persists then I'll check with the professionals again.
