Coronal plane alignment of the knee phenotypes and ankle joint coronal plane alignment patterns in Egyptian population

Figure 1 Radiological assessment and classification details. A: Long-leg, standing anteroposterior (hip to knee to ankle radiograph showing how mechanical lateral distal femoral angle, medial proximal tibial angle, and tibial plafond horizontal angle were measured; B: Schematic representation of the coronal plane alignment of the knee classification following MacDessi et al[5] description; C: Ankle joint line orientation directions and types. mLDFA: Mechanical lateral distal femoral angle; MPTA: Medial proximal tibial angle; TPHA: Tibial plateau horizontal angle; aHKA: Arithmetic hip, knee, and ankle; AJLO: Ankle joint line orientation.
