Relationship between lower limb torsion and coronal morphologies of the femur and tibia in patients with medial knee osteoarthritis

Table 2 Radiographic and CT data

HKA	−8.8 ± 3.4° (− 0.5°−− 16.4°)
mLDFA	88.4 ± 2.6° (83.1°–95.5°)
mMPTA	84.4 ± 2.5° (78.9°–89.0°)
Femoral internal torsion	12.2 ± 8.5° (− 6.5°–28.9°)
Tibial external torsion	18.0 ± 7.4° (2.6°–37.8°)
Sum of femoral and tibial torsions	5.9 ± 11.2° (− 19.8°–39.0°)

Data are presented mean ± standard deviation with range in the parenthesis. The mLDFA, mechanical lateral distal femoral angle; mMPTA, mechanical medial proximal tibial angle; HKA, hip-knee-ankle angle. A positive value means valgus alignment
