| mLDFA | 0.821 (0.744–0.875) | 0.837 (0.767–0.886) |
| JLCA | 0.976 (0.966–0.983) | 0.956 (0.933–0.970) |
| MFCA/TEA | 0.899 (0.855–0.929) | 0.819 (0.741–0.874) |
| PCA/TEA | 0.951 (0.921–0.970) | 0.813 (0.699–0.884) |

Values are expressed as the mean intraclass correlation coefficient (ICC) with 95% CI in parentheses. HKA—hip-knee-ankle axis, MPTA—medial proximal tibial angle, mLDFA—mechanical lateral distal femoral angle, JLCA—joint-line convergence angle, MFCA/TEA—mid-flexion condylar axis/trans-epicondylar axis, PCA/TEA—posterior condylar axis/trans-epicondylar axis, PCOA—popliteal crease obliquity angle.
