I have knee pain when I run."How we do one thing is how we do all things."

I am not sure who made this statement first, otherwise we would share attributes to it, but it is a good quote. If you saw the back of my truck, you would know what my closet looks like at home. Organization is not a top shelf priority of mine. I can neve remember where i put anything.

IF this is how someone does a double support jump on the up and down loading phases, what do you think is likely to happen in single leg hops ? how about forward hops with movement? Forget about it. Oh wait, that is what running is, forward hops.

Simple principle today, sometimes the best place to start with someone's suspected problematic loading strategies, is to peel it back to the simplest root strategies of the more complex faulty strategy.
All to often we just "run", but we have no idea how to load and unload effectively. If some one cannot double support jump with controllable skill, how then will they single leg hop in place with controlled skill, let alone hop forward progressively with controlled skill, and then do so alternating leg to leg, (running) with controlled skill ?

Sometimes the solution is not an orthotic, or a more stable shoe, or some magical elixer corrective homework seen on a guru's youtube feed.
Sometimes, we just need to start from the beginning. Sometimes it is that simple, start from the start, and build up from there. Sometimes there is no magic, it is just simple progressive loading, which to some will seem too crude and wasteful, and to others who truly "get it", magical.

Sometimes, "how we do one thing, is how we do all things".

More on landing mechanics.
Here is a recent article on landing mechanics. This article talks about the landing mechanics far past where I feel the first stage of vulnerability is, which is initial forefoot load, as i discuss in the video pertaining to landing from a jump or if sprinting (forefoot loading). IF landing occurs in low gear (lateral half of the forefoot), inversion risks are higher.
The medial foot tripod, high gear toe off (1st and 2nd mets) is where we should be taking off from, and landing initially upon. Anything lateral is vulnerable without the lateral column strength (lateral gastrocsoleus complex, peronei longus/brevis).
This article talks about knee flexion angles and ACL vulnerability, far after this initial loading response. The article some valid conclusions in that phase.

The effect of lower extremity fatigue on shock attenuation during single-leg landing.

Thank goodness the body can compensate. Here is a perfect example of this discussed in this study.
“ … it has been shown that a fatigued muscle decreases the body’s ability to attenuate shock from running. The purpose of the study was to determine the effect of lower extremity fatigue on shock attenuation and joint mechanics during a single-leg drop landing.”
This study suggests that as one part fatigued, the joint and muscle strategies elsewhere in the limb made up for it.
“Hip and knee flexion increased and ankle plantarflexion decreased at touchdown with fatigue. Hip joint work increased and ankle work decreased.” The results suggested that the lower extremity is able to adapt to fatigue though altering kinematics at impact and redistributing work to larger proximal muscles.
