A prospective randomized study. None of the OCFs examined in this study caused mechanical symptoms due to joint incarceration. Studies on redislocation rate after various treatments of acute lateral patellar dislocation with OCF from the medial side of the patella are insufficient to draw solid conclusion regarding how it affects clinical outcome. Reduction of an acute dislocation can usually be achieved simply by straightening the knee. Nomura et al. 1, 2, 10 MRI and/or computed tomography (CT) scanning should be considered in most young patients after a patellar dislocation associated with a large joint effusion/hemarthrosis to identify size and to locate and estimate the condition of these fractures. Eighteen children (13 females, 5 males) aged 11 to 15 years (mean age 13.1 years) with osteochondral fracture (OCF) of the knee joint were treated at the authors' institution.

This was a retrospective study of 69 consecutive patients with mean age of 19.6 years (range, 15 to 41 years) who were followed up over a 2-year period after first-time APD. Simple x-ray, CT, and MRI were carefully evaluated to inspect existence of medial patellar OCF. For adults, such a condition usually requires surgery. The mean size of the OCF fragments from the inferomedial facet was 16 (major axis) × 12 mm (minor axis). orcid Functional outcomes of each group were assessed using the Kujala score and International Knee Documentation Committee Subjective Knee Form (IKDC SKF) questionnaire at initial presentation and final follow-up [23, 24].
