Most often if it is a relatively strong person who has been doing some
training it doesn't mean either. It tends to mean you have a relatively
weak posterior chain. So you are compensating. I really don't see
stretching (at least conventional stretching) helping.
During hip extension and knee extension you have a number of two joint
muscles working - rectus femoris is a knee extensor, but a hip flexor
for example. You also have the hamstrings which are hip extensors, but
knee flexors, as well as sartorius and gracialis. So hip extension and
knee extension is a very complex movement pattern since the two joint
muscles are at competing ends. The knees buckling is almost always
accompanied by the pelvis tilting because the gluts can't stabilize the
conflicting pulls of the two joint muscles. People see the knees
buckling, but they miss the accompanying pelvis tilt. The pelvis tilt
tends to be more subtle.
So despite all the fancy anatomy, the solution tends to be easy. Wide
stance box squats where they focus on pushing the butt back onto the box
and keeping the knees out. Sumo deadlifts as well.
Another trick is to tell the person to imagine they are clenching a
quarter between their butt cheeks as they squat. They tend to keep the
gluts activated then.
Fatal flaw is having the person squat lower than their ability to keep
the pelvis aligned. I advocate ass-to-the-grass squats, but only if the
pelvis alignment can be maintained - neutral back and no 'wink' of the
ass. Once again, since the focus on the box is to slide back onto the
surface like you are trying to push a piece of paper back the box squat
is really an exercise that focused on pelvis alignment.
Normal caveats about controlling the weight, not 'thumping' onto the box
apply. Box is lowered over time as the person learns to stabilize the
pelvis.
