Background: Although MRI prognostic features for juvenile osteochondritis dissecans (JOCD) have been determined, the natural history of JOCD on serial MRI has not been fully documented.
Objectives: To document the natural history of JOCD on serial MRI and to correlate this with arthroscopy and clinical outcome over a 5-year follow-up.
Materials And Methods: Twenty-one knees in 19 patients (15 boys, 4 girls; age range 5-15 years) with JOCD underwent MRI and clinical follow-up over 5 years.
