Evaluating the C-Score from Weight-Bearing CT as a Quantitative Imaging Biomarker for Worsening Knee Osteoarthritis Structure and Pain in the Multicenter Osteoarthritis Study.
OBJECTIVE Investigate a novel "C-score" metric of femoral bone shape, derived from weight-bearing-CT (WBCT), as an imaging biomarker for knee osteoarthritis (OA) structural progression and pain worsening in men and women with, and at increased risk for, symptomatic knee OA.
