The knot is simply where the branch/stem heals from a break. It forms a knot just like we have scare tissue. However, unlike us, this knot is beneficial. It acts as a second hormonal dispatch point. It is normally seen when supercropping. Besides evening teh canopy, SC is used to push hormones to the bud sites. Most growers report the section above the break to be stronger, and more bountiful. This is normally thought to be for photos only, but does the same thing on autos. Just be warned on a auto, it is an advanced training, and can have negative effects. Here are a few knots I have mad recently.
Night Terror OG, Multi topped, supercropped, and strapred down like a mental patient.

I also use it to stunt growth. Rather than bending it over like the above pic, I'll just crush the stem, and let it heal in the natural direction. (less likely to actually form a knot) It can be a catch 22 as, the knot can make it grow. When I do this would normally be towards the end of stretch, and I am running out of room.
Done correct, it just makes the stem tough as nails, and slightly bulges out...

Done incorrectly, you get the knot, and that top grows more. This cola had to be constantly moved, and tied so it would not grow in to the light. (these 2 pics are the same plant) I just waned to break the inner tissues, not actually crack the skin as pictured.
