called internal tibial torsion. A child age 3 or older may experience a turning-in of the femur, or thighbone, called medial femoral torsion. This is sometimes referred to as femoral anteversion.

Most children with femoral anteversion show complete correction over the course of years. By the age of 10 years, 80% of them start to walk normally, with the torsion reduced to near normal degrees.
