MRI Abnormalities of the Acetabular Labrum and Articular Cartilage Are Common in Healed Legg-Calvé-Perthes Disease with Residual Deformities of the Hip

Abstract

On the basis of magnetic resonance imaging evaluation of the hip, labral and cartilage abnormalities were a common finding in patients with healed Legg-Calvé-Perthes disease. Our results suggest that hip deformities are significantly associated with labral and cartilage abnormalities on magnetic resonance imaging, and the main predisposing factor was the asphericity of the femoral head with a reduced femoral head-neck offset.
