Femoral anteversion and physical performance in adolescent and adult life.

The relationship between excessive idiopathic femoral anteversion and physical performance in adolescent and adult subjects is explored in 9 adults with excessive anteversion and in 10 age-matched controls subjected to extensive physical performance testing. Two hundred and forty-nine high school students were studied by assessing running speed and measuring hip rotation. Those with greatest internal rotation were isolated and compared with the total group. In both studies no relationship could be found between excessive anterversion and physical performance.
