(A) Maximum contact pressures in the anterior (A) and posterior (P) maltranlations (mm) of femoral component relative to the neutral contact alignment at 0° of flexion; (B) Maximum contact pressures in the medial (M) and lateral (L) maltranlations (mm) of femoral component relative to the neutral contact alignment at 0° of flexion; (C) Maximum contact pressures in the internal malrotation (IR) and external malrotation (ER) (degrees) of femoral component relative to the neutral contact alignment at 0° of flexion. (*) indicates there is statistically difference between fixed-bearing and mobile-bearing design.
