Complete Physical Observe gait walking and running with the entire lower extremity visible for isolated observation of the foot, leg, knee and thigh. Observe for rotation. If patella is internally rotated, suspect medial femoral anteversion. Angle from the foot to the line of progression during ambulation. Foot vs. Straight line.
Medial rotation is signified by a negative number.
Significance is of nonspecific rotational deformity. Estimation of the foot progression angle is done by watching the child walk naturally toward the physician. The average deviation of the axis is then measured for each foot relative to the line of progression. Drawing a line at the center of the plantar forefoot should line up with the 2nd or 3rd ray. If the line deviates laterally metatarsus adductus.
