Abstract We conducted a longitudinal study duration 2 years including 294 individuals mean age 45 years 58 female in order to examine associations between meniscal extrusion knee structure radiographic changes and risk factors for osteoarthritis OA in a largely non-osteoarthritic cohort. Meniscal extrusion tibiofemoral cartilage defect score and cartilage volume and tibial plateau bone area were determined using T1-weighted fat-saturated magnetic resonance imaging. At baseline the presence of medial meniscal extrusion was significantly associated with body mass index odds ratio OR per kg m2 95 confidence
