Forefoot varus and patellofemoral cartilage damage.
/So you just give everyone a FOOT TRIPOD and ANKLE ROCKER exercise and think the world will all be sunshine and rainbows huh ? Beware all you movement wizards, there is far more to it !
"Knowing enough to think you're doing it right, but not enough to know you're doing it wrong." - Neil deGrasse Tyson
So your client has knee pain huh ? Look far and wide, this is a global game amigos.
"Of the 51% of limbs with forefoot varus, 91.3% had medial and 78.3% had lateral PFJ cartilage damage. . . . . this study suggest a relationship between forefoot varus and medial PFJ cartilage damage in older adults"- Lufler et al. (study link below)
*If you do not know your client has a rigid forefoot varus, and they have hip or low back pain and cannot keep their glutes activated and participating in movements, how long are you going to fail your client ? The forefoot varus may need addressed because of the excessive, abrupt degree of internal spin on the limb.
If you are truly going to treat people, people who move (yes, that means everyone !), you have to know feet and gait, BOTH. Your knowledge must go far past rudimentary knowledge of:
- high / low arch
- flat feet
- prontation and supination
- orthotics and footbeds
You will have to know your foot types, you will have to understand shoe anatomy, foot anatomy, flexible semi-flexible and rigid foot types, compensated and uncompensated foot types, and of course know how each of these responds under various loading responses. Forefoot varus will load differently in cutting sports than in sagittal locomotion such as walking and running (both of which are different even in themselves despite both being sagittal). A foot that looks like it has a flat collapsed arch has far more to it than that, and thus remedy and intervention MUST go far beyond rudimentary interventions like a "stability shoe" or orthotic. Are you practicing, coaching, training and being part of your client's solution, or are you part of the problem ? If you want to get better at this stuff, we cover it all in our several hour (very difficult for some) National Shoe Fit program (the link is on our website if you wish to become a foot/gait/shoe jediwww.thegaitguys.com). Do not be mistaken, this is far more than "shoe Fit". To know how to properly shoe fit someone, you have to know the foot types and how they compensate, load, and respond. Without this knowledge, you are just another bump in the "road of problems" without ample solutions.
