• BACKGROUND
    • The purpose of this study was to evaluate radiographic-based classification systems for osteochondritis dissecans (OCD) of the capitellum and determine their agreement with intraoperative findings.
  • METHODS
    • Using PRISMA guidelines, we analyzed 44 studies utilizing a total of 19 classification systems.
  • RESULTS
    • Magnetic resonance imaging (MRI)-based systems showed better predictive value of intraoperative staging, and the Itsubo and Kohyama classifications showed best predictive value for lesion stability.
  • CONCLUSIONS
    • No classification system effectively correlated with intraoperative findings. A combination of radiograph, MRI, and computed tomography will most accurately determine OCD lesion stability.
  • LEVEL OF EVIDENCE
    • IV, Systematic Review.
