Table 4 Measurements of angles between the suggested anatomical references and axis perpendicular to the ideal cutting plane with their advantages
Femur | Tibia | |
|---|---|---|
Suggested anatomical reference | Angle bisector of lateral and medial cortical lines (FCAB) | Central part of tibial canal accessed through an entry point at the knee center |
Mean angle between anatomical reference and axis perpendicular to ideal cutting plane | Distal region: 0.7° (SD = 1.4) Central region: 0.1° (SD = 1.2) | 0.5° (SD = 0.6) |
Advantage | Most accurate at both distal and central region | No need of preoperative plan to determine the entry hole |
