Microfracture is a well‐established treatment procedure for chondral defects in high‐demand population with good short‐term results. The purpose of our study was to evaluate long‐term clinical outcome of microfracture treatment in athletes with full‐thickness chondral defects.

Between 1991 and 2001, 170 patients were treated with microfracture for full‐thickness knee chondral lesions at our institute and 67 of them were included in this study and prospectively followed up. Sixty‐one athletes (91 %) were available at final follow‐up (average 15.1 years). Average lesion size was 401 ± 27 mm².
