The influence of defect stiffness on local contact metrics.

The effect of different elastic moduli on the average contact pressure (A), contact area (B), contact force (C) and average compresssive strain (D) inside and surrounding the defect and medial compartment of the anterior-central defect in the medial femur throughout the stance phase of gait (mean ± standard deviation). Significant differences compared to the reference simulation (gray line) at 5% significance level are indicated by dots on the error bar.
