The dataset contains material to supplement the paper “Understanding the differences in wear testing method standards for total knee replacement” including: images of Figures 1 to 12 inclusive; the graphical abstract; the raw data underpinning the figures; additional points throughout the cycle to supplement Figure 4.b: (Computational contact scars at 15%, 50%, and 85% through the gait cycle using different displacement control test methods are presented in Figure 4b, this additional data shows computational contact scars at every 5% interval) and Figure 10.b: (Computational contact scars at 15%, 50%, and 85% through the gait cycle using ISO-14243-1-2009 force control test method are presented in Figure 10b, this additional data shows computational contact scars at every 5% interval)
