BACKGROUND: This study aimed to elucidate the relationship between ankle morphology and the size of non-trauma related osteochondral lesions of the talus (OLT), because approximately half the OLT found in children is of unknown origin. METHODS: 34 ankles in 30 skeletally immature children with OLTs who underwent preoperative magnetic resonance imaging (MRI) were evaluated. Parameters measured included area of the OLT, tibial axis-medial malleolus angle (TMM), malleolar width (MalW), and talar surface angle (TSA; defined as the angle between the line perpendicular to the mid-diaphysis of the tibia and the talar joint surface; medial inclination, positive)...
