Femoral Anteversion is a condition where the femoral neck leans forward with respect to the rest of the femur (long bone in the thigh) causing the leg to rotate inward.
This causes the knee and foot to turn in.
Femoral Anteversion is congenital (presents at birth) and often runs in the family.
It usually is bilateral (on both sides).
The tibia (shin bone can compensate for this and turn out which causes a malalignment at the knee.
Where the hip goes inward and tibia goes outward.
All of the abnormalities in the leg cause increased stress on the knee due to the bones not being aligned appropriately.
This can cause pain in the hip, knee or ankle and can wear the joints down over time
It is usually more comfortable to sit in a W-sit (feet going out and knees in, vs sitting crossed legged on the floor) but you want to avoid this as much as you can.
Younger kids often present with no pain.
They will present with poor control of their muscles especially eccentrically like going down stairs, tripping, difficulty running
with excessive gait deviations.
Physical therapy can assist with improving the control of the musculature and promote improved alignment.
Especially when they are seen young and still growing.
Sometimes a night splint is used to help correct the torsion. (rotation in the tibia)
As kids mature, pain is more prevalent.
Especially in the knee. Patella instability can be a result of the alignment of the bones.
Early arthritis can occur.
Conservative treatment (physical therapy, knee braces, and taping) is usually successful treating this condition.
It usually gets worse during times of growth, so the exercises are important to continue to do throughout the growing time.
In severe cases surgery may be needed, but that is rare.
