© The Author(s) 2020.Background: The aim of this study was to compare the clinical and magnetic resonance imaging (MRI) outcomes of arthroscopic microfracture (MF) plus chitosan-glycerol phosphate/blood implant and MF alone for the treatment of the osteochondral lesions of the talus (OCLTs). Methods: Patients who underwent either MF plus chitosan (group 1, n = 32) or MF alone (group 2, n = 31) between 2015 and 2019 in 2 separate time periods were retrospectively analyzed. Visual analog scale (VAS) score and American Orthopaedic Foot & Ankle Society (AOFAS) score were used for clinical evaluation. The magnetic resonance observation of cartilage repair tissue (MOCART) system was used for MRI evaluation. The mean follow-up time was 32 ± 13 months (range, 12-61 months). Results: Postoperatively, we detected significant improvements in both groups in terms of VAS and AOFAS scores. However, we observed no statistically significant difference between groups in terms of clinical scores, except the mean VAS function score, which was significantly higher in group 1 (P =.022). According to MOCART scale, complete repair with the filling of the chondral defect and intactness of the surface of the repair tissue were more common in group 1. However, these parameters did not significantly differ between groups (P =.257 and.242, respectively). Conclusion: Arthroscopic MF plus chitosan glycerol phosphate/blood implant did not result in better clinical and MRI outcomes compared with MF alone in the treatment of OCLTs. Level of Evidence: Level III, retrospective comparative study.
