As others have noted – core strength can and does impact the entire body. Depending on your activities, your knee’s can easily take a considerable amount of damage.

If you notice a trigger point on your quads – DEFINITELY hit those up. I suggest using a softball or lacrosse ball – not a foam roller.

If you are able – I also suggest seeing a PT that is qualified in dry needling to hit up those trigger points. You’ll get tremendous bang for your buck if you go this route – but it won’t fix everything.
