Painscience.com and Hargrove's "A Guide To Better Movement" are pretty good for a model of predictive processing and the roll of the nervous system in chronic pain and movement. I still don't feel like I have a good model of bone and joint health in general, however. Eg, I'm currently nursing a flare up of patelo-femoral pain in my left knee. I've done a number of things over the past few months to deal with it, with some success, including buying and reading Painscience's book length patelo-femoral tutorial. Recently I've had a bit of pain in my foot, possibly in the tibiocalcaneal or tibionavicular tendons. I find that even though I now know a fair amount about PFS and the way the nervous system processes pain, these models don't generalize well to sporadic, idiopathic pain in another joint.
Possibly the answer is: "lol that model doesn't exist", or "lol wanna get a phd?" but if there are good resources, I'd be an eager consumer.
A sub-question that I'm particularly interested in is: what, if anything, is know about the relationship between base line muscle tone and joint issues? I have good reason to think my baseline muscle tone is higher than average.
Can I clarify before I spend time writing a long answer - You are looking for a model that explains why you've now got pain in your foot (with a history of knee pain)?
If that's what you want to know, it's not complicated - pain spreads over time.
How I'd briefly explain things:
We alter position to avoid pain.
Positional changes alter the stresses throughout the body (we are connected from head to fingers to toes).
Stresses are unevenly distributed when the body is not in an ideal posture.
Alterations due to pain = not good for posture.
Poor posture = Pain.
One problem area spreads to another as the body keeps adjusting to avoid pain.

I've written a fair bit about muscles, connective tissues and pain in this post.
I could write specifics about knee pain if want.
Otherwise, some good resources:

I watched a few videos and contact improv looks great. (Full disclosure I watched the videos x2 speed I've little patience watching most stuff). For people in a good enough physical condition, and relaxed enough to go with it, I can see it being beneficial and a lot of fun. (5 years ago I would have hated the idea because back then movement = pain, pain, pain and I couldn't have let go to move) It looks like free-flowing movement, guided instinctively by the body rather than the brain trying to control and direct.
