Bone Marrow Edema Injury Patterns in the Pediatric Knee: An MRI Study.

ABSTRACT:

Background

Symptomatic pediatric patients referred for magnetic resonance imaging (MRI) commonly present with traumatic bone marrow edema (BME) patterns.

Purpose

We sought to associate discrete MRI patterns of BME with specific injury mechanisms in pediatric knee injuries to classify injury patterns by anatomical location of the BME. We aimed to group these into 6 patterns: patellar dislocation, extensor mechanism overload, hyperextension, single compartment impaction, ligament avulsion/translation, and direct contusion.

Methods

We retrospectively reviewed 314 MRIs performed with a standard protocol on symptomatic patients aged 3 to 18 years at 1 institution. Our analysis included images, reports, and traumatic BME patterns. A musculoskeletal radiologist and orthopedi
