Reliability of Semiautomated Computational Methods for Estimating Tibiofemoral Contact Stress in the Multicenter Osteoarthritis Study

<table>Methodology for subject-specific, population-wide investigations of habitual contact stress exposure in the knee. MR images are segmented to produce bone models (a and b), which are aligned to a standing radiograph using a ray casting algorithm (c). Contact stress is computed using discrete element analysis (d).</table>
