The sport podiatrist analyses the gait line, the swing phase, and the ankle roll (absolute)
The gait line allows us to quickly see how the step rolls and the associated contact times. The patient’s foot, whether left or right, pronates. We also note that the contact times are greater on the left, the foot that is the most deformed.
The ankle roll is used to obtain the precise angles of deformation. In this case, it allowed me to make corrections under the heel, as I had not identified this need during the examinations that I had done before.
I carried out the standard examinations that I typically do, a questionnaire and an examination seated in a chair, stationary and standing on one foot.
Upon questioning, we learned that the patient runs regularly, and for several months he has been experiencing from pain in the external face of the knee, which appeared progressively and eventually on both sides.
In a stationary exam, he has very few deformations, the calcaneus is centred, and we note an increasing collapse of the weaker bilateral midfoot.
When observing the patient standing on one foot with the knee bent, we observe a pronation in the foot, and a knee that angles toward the inside. I also carried out a dynamic test and video sequences.
Here we see a pronation of both feet, a genu valgum.
Iliotibial band syndrome is due in this case to a pronation of the foot that occurs dynamically and is accentuated by running as there is more weight on each support.
This pronation consequently provokes a genu valgum combined with an internal rotation of the knee. The ITBS limits the internal rotation of the knee, it experiences excessive traction and inflammation occurs.
