Abstract

Purpose: To evaluate the clinical results after microfracture surgery for full-thickness chondral lesion of the knee. Materials and Methods: Thrity-seven patients, who had underwent microfracture surgery for full-thickness chondral lesion of the knee between January 1999 and December 2005, were reviewed. Their mean age at the time of operation was 31 years (range, 21~38 years) and mean follow up period was 2.7 years. All patients were reviewd every 6 months after operation. Clinical outcomes were evaluated by activity of daily living (ADL), Tegner activity scale, International Knee Documentation Committee (IKDC) knee examination form, Lysholm score and satisfaction of treatment. Results: ADL and Tegner activity score improved in 83% of patients during first 18 months, but decreased during next 6months. IKDC score improved from 58 points at operation time to 86 points after 12 months, but decreased to 79 points and 68 points at 18 and 24 months after operation, respectively. Also, Lysholm score improved from 61 points at operation time to 89 points after 12 months, to 92 points after 18 months, but 73 points after 24 months. At the last follow-up, 22 patients were excellent or good in satisfaction of treatment, whereas 12 patients were fair, 3 patients were poor. Conclusion: Microfracture surgery for full-thickness chondral lesion of the knee has a good functional improvement for first 12 months after operation, but its effectiveness has decreased over time.
