Treatment of Unstable Osteochondral Dissecans Lesion of the Knee Joint Using Autologous Osteochondral Plug

Abstract

Clinical evaluation was performed by comparing the preoperative and last follow-up scores of Lysholm score and subjective International Knee Documentation Committee (IKDC) score. Results: All patients were male and the average age was 19.1 years. Of the 19 cases, there were 16 cases of medial femoral condyle lateral side lesion, 2 cases of lateral femoral condyle articular surface, and 1 case of femoral intercondylar notch lesions. The average size of the lesion was 5.68 mm 2 , and average use of osteochodral plugs were 4.3. Average follow-up period was 38 months. Preoperative Lysholm score, IKDC subjective score showed significant improvement. Conclusion: Fixation with autologous osteochondral plugs for unstable OCD uses the remnant tissues therefore conserving it, which is thought to be the positive aspect of this type of operation.
