Table 4: Medial and lateral contact forces for the different configurations and for different stem lengths and cementing techniques. The detailed values for the four different models are reported in Tables 6-9. Figure 4: Input force, contact force and contact area relative to different varus/valgus angles for the cemented 50 mm stem. Figure 5: Average von Mises stresses in four regions of interest ((**A**): ROI 1, (**B**): ROI 3, (**C**): ROI 5, (**D**): ROI 7) for the different prosthesis features, according to the varus/valgus angles addressed.
