Fig. 1 Ensemble averages showing the time-course pattern of the (A) internal sagittal plane knee joint moment, (B) internal KAM, and (C) compressive knee joint force. Peak moments and forces used in the statistical analyses are shown with text-arrows. Please note that the temporal occurrence of the peak values may not match those indicated on this figure. On Fig. 1C the initial peak is considered artificial and is ignored during the data analysis. On 1C, the axial impulse (i.e., area under the curve) is shown as shaded. HS=heel-strike and TO=toe-off.

Fig. 2 Scatter plot illustrating the relationship between weight loss and change in knee joint compressive force adjusted for age, gender, alignment and changes in both walking speed and pain. Full line shows the best-fit linear regression with 95% confidence intervals (dotted lines). The slope (β-value) is significantly different from zero (P=0.029).
