Good correlation between two- and three–dimensional parameters of intercondylar notch morphology in the pediatric knee: a cadaveric computed tomography study

Introduction/objectives

Distal femoral morphology is associated with ligamentous injuries, including anterior cruciate ligament (ACL) tears, and may influence treatment outcomes. While intercondylar notch morphology has been extensively studied in adults using different radiographic parameters, its developmental anatomy in pediatric populations remains poorly understood. The objective of this study is to describe intercondylar notch morphology in skeletally immature specimens using computed tomography (CT). We hypothesized that 1) notch height and notch width are positively correlated with age, while the notch width index (NWI) remains stable throughout growth, and 2) that commonly used two-dimensional notch measurements would show no correlation with three-dimensional notch volume.
