Obesity, Moderate Knee Osteoarthritis, and Knee Joint Dynamics

Obesity is a highly cited risk factor for knee osteoarthritis (OA) associated with increased risk of development of OA and accelerated disease progression. Rates of obesity are increasing internationally, and while obesity is well established as a risk factor, the precise role of obesity in knee OA pathogenesis and progression is not as clearly understood. Mechanical loading has been implicated as an important factor in knee OA initiation and progression. The purpose of this thesis was to further examine the roles of moderate knee OA disease presence and obesity on knee joint mechanics during gait, and to characterize their mechanical interaction. Two methods have been applied. First, principal component analysis has been applied to resultant waveforms from gait analysis and second, a sagittal plane joint contact force model has been applied. Using both methods, statistical differences in biomechanical loading has been associated with obesity, moderate knee OA, and their interaction.
