【 摘 要 】

Category:AnkleIntroduction/Purpose:Subchondral bone marrow edema (BME) has been associated with articular cartilage loss, with the potential to be a negative prognostic indicator for clinical outcome following microfracture. However, no single study has investigated the influence of BME on clinical outcome following microfracture for osteochondral lesions of the talus (OLT) at mid-term follow-up. The purpose of this study was to clarify the influence of postoperative subchondral BME on the clinical outcome in patients treated with microfracture for OLT at both short- and mid-term.Methods:Patients who underwent microfracture between 2008 and 2013 were assessed at 2- and 4-year postoperative follow-up. BME was evaluated using magnetic resonance imaging (MRI), and the presence of subchondral BME was determined with fat-suppressed T2-weighted sequences. BME was graded on a 0-3 scale based on the relation to total talar volume as follows: 0, no BME; 1, <25% of talar volume; 2, 25%<, >50% of talar volume; 3, >5...
