I have a Peavey Vyper 75 watt and today I was putting some Christmas stuff into the attic and some stuff fell and hit the low and mid knobs off. I became very worried when I saw the knobs off. I put them back on and they worked just fine, but are there any concerns due to this issue so I can fix them right away?

If things are working, they're working. Aside from checking to see if anything's broken/loose, there's nothing to do. Just be thankful it still works.
If they're working it's all good. Test both knobs.
