a The DACA was the line connecting two points on the anterior cortex at 5 cm (point e) and 10 cm (point f) proximal to L (L was the tangent line of distal femur parallel to the knee line, the knee line was the junction between the shaft and the condylar region). sMA was the line connecting DPIN (point g) and the center of femoral head (point h). DACSMA was the angle between sMA and DACA, and L1 was parallel to DACA. b sDAA was the midline drawn in the distal quarter of femoral shaft. DACSDAA was the angle between DACA and sDAA, and L2 was parallel to DACA. c SMADAA was the angle between sMA and sDAA, and L3 was parallel to sDAA
