This retrospective study was designed to evaluate the hypothesis that open reduction internal fixation (ORIF) of an unstable osteochondritis dissecans (OCD) lesion results in a high percentage of acceptable outcomes at long-term follow-up.


Eight patients who had been treated with ORIF for unstable knee OCD lesions were identified. Long-term outcomes were assessed with a Subjective Knee Evaluation Form and Knee Examination Form of the International Knee Documentation Committee (IKDC 2000) and an OCD specific Hughston rating scale.


All lesions were healed and stable to arthroscopic probing at 3 months. At the average follow-up of 14.8 years (range 12–21 years), the mean IKDC subjective score was 80.9. In IKDC examination form, six patients reached group A (normal) and two patients reached groups B (near normal) and C (abnormal), respectively. According to Hughston criteria, three patients were rated excellent, three good, one fair, and one poor.


We recommend aggressive attempts to preserve articular cartilage in OCD.
