[Abstract] Objective: To analyze MRI characteristics of osteochondral injury patterns in adolescents after acute lateral patellar dislocation.Materials and Methods: MR images of 41 adolescents after acute lateral patellar dislocation were retrospectively reviewed. Routine MR scanning was performed in axial, sagittal and coronal planes, including T1WI, T2WI and fat saturation sequence.Results: The prevalence rate of osteochondral injury was 90.2% (37/41) in adolescent group after acute lateral patellar dislocation. The prevalence rate of Ⅰ, Ⅱ, Ⅲ, Ⅳ degree were 10.5%, 12.2%, 24.5%, 52.6% in adolescent group. The prevalence rate of osteochondral injury at patellar attachment, femoral attachment and both patellar-femoral attachment were 32.4%, 13.5%, 54.0% in adolescent group.Conclusion: Ⅲ, Ⅳ injury and at patellar attachment, both patellar-femoral attachment were most easily occurred in adolescents.
