- All parameter values are reported as mean (standard deviation)
- Aspect ratio, the ratio between the anteroposterior dimension of the lateral condyles and the femoral mediolateral dimension; Arc angle, the angulation between the most proximal cutting plane and the most distal cutting plane; Proximal-end angle, the angulation between the most proximal cutting plane and the 0° cutting plane; Distal-end angle, the angulation between the most distal cutting plane and the 90° cutting plane
- *There were significant differences when comparing type 45° with types 60° (p1, p4), 75° (p2, p5), and 90° (p3, p6) in terms of aspect ratio and distal-end angle, respectively
