AL anterolateral, AM anteromedial, APL anteroposterior length of lateral femoral condyle, APM anteroposterior length of medial femoral condyle, CEA clinical epicondylar axis, CTA condylar twist angle, DDH developmental dysplasia of the hip, FNA femoral neck anteversion, KRA knee rotation angle, PL posterolateral, PM posteromedial
  2. Values are mean ± standard deviation.
