MRI of congenital and developmental abnormalities of the knee

The knee joint is the one of the most common locations for congenital and developmental musculoskeletal abnormalities. Initial imaging of the knee joint should always begin with conventional radiographs. However, evaluation of the bone marrow, cartilaginous, ligamentous, and other soft-tissue components of the knee joint are better characterized with magnetic resonance imaging (MRI). We present the MRI findings of prevalent congenital and developmental abnormalities in the paediatric knee with particular emphasis on the components of the growing skeleton.
