The MPTA is determined by measuring the angle created by a line of the central axis of the tibia and a second line drawn across the proximal tibial epiphyseal surface or joint line. In a similar way, LDTA is measured by the angle created by a line of central axis of the tibia and a second line drawn across the distal tibial epiphyseal surface or talar plafondBack to article page
