That and memory foam / gel pads in your shoes. I walk a lot since the lock down and I've had knee issues in the past. Good gel pads help and using your knees with light exercise actually improves things. I Mostly wear sneakers. Hiking shoes tend to be a bit more rigid and have less shock absorption.

The poles might help as well. Nordic walking, is a thing that a lot of cross country skiers do in Scandinavia to stay in shape during the summer. Also nice for people with balance issues or weak backs of course. Done properly, it makes for an intensive workout.

You should not get kee problems from walking. Maybe your gait is somewhat unnatural?

Fortunately I never had problems like that but I am sure using barefoot shoes (Fivefinger in my case) improved how I walk. When I am not using those I use zero drop Trailrunners (Altra Lone Peak) which kind of force you to use your front foot more.

Depends on the terrain.

I can walk all day on reasonably level terrain with no knee issues. I prefer poles when there is appreciable climb and I absolutely must have poles and compression sleeves on my knees for any substantial descents.

I always hike with poles but if the terrain is level enough they'll be simply in one hand or possibly stowed on my pack. If I'm on a mountain I'll be using them frequently.

Nordic walking seems to be popular among people of late middle age in Germany too.
