Runner's
knees often hurt because of torque in the joint created
by over-pronation.
Torque is created when the bones in the lower leg, (the
tibia and fibula) rotate inward more than the thigh bone
(the femur). Some torque in the knee is natural, but too
much often leads to pain andinjury. By reducing pronation
arch supports help to relieve pressure on the knee.
Feet Relief recommends using arch supports as part of
a complete knee pain treatment plan. Arch supports re-align
the bones of the ankle and knee and reduce tissue strain
caused by over-pronation. Feet Relief also recommends
wearing good shoes with a lot of support. To learn more

"Patellofemoral Pain Syndrome: A Review and Guidelines
for Treatment"

| "Arch
supports or custom orthotics can be helpful in patients
with a wide variety of lower extremity complaints, including
patellofemoral pain.33,34 Although the reasons are not
entirely clear, an arch support may improve lower extremity
biomechanics by preventing overpronation in pes planus
and by providing a broader base of support for the normal
or pes cavus foot. Over-the-counter arch supports are
a reasonable and relatively inexpensive initial suggestion." |
