abstract
PURPOSE: The purpose of this study was to identify the biomechanical determinants of altered knee joint loads consequent to 18 months of an intensive dietary intervention either with or without exercise. Our primary hypothesis was that weight loss and quadriceps force would have the strongest, positive associations with each of the knee joint load outcomes (tibiofemoral (TF) compressive force, patellofemoral (PF) compressive force, anteroposterior (AP) shear force, and internal knee abduction moment (iKAM)). We also hypothesized that gait speed, knee flexion angle, and internal knee extensor moment would display positive associations with each of the knee force outcome variables.
