[Osteochondritis dissecans of the ankle].

PURPOSE: The aim of this study was to determine the efficacy of the microfracture method in the treatment of symptomatic osteochondral lesion of the talus.

MATERIALS AND

METHODS

24 patients operated by the mentioned method were prospectively followed-up. Standard radiological treatment was performed in all patients, ankle CT was performed in 10 patients, and MR was performed in 8 patients. Patients' subjective satisfaction with operation was assessed by SANE and Martin's score, while the objective function was assessed by AOFAS and Freiburg's score.

RESULTS

The mean preoperative AOFAS score was 53 (from 31 to 61), while the mean postoperative AOFAS score was 87.5 (from 81 to 100). Postoperative Freiburg's score was 89.5 (from 76 to 100). The distribution of treatment outcomes was evaluated by the Martin's score and it revealed excellent, good and satisfying results in 94.5% patients, while the distribution of outcomes by the SANE questionnaire revealed excellent and good result in 91.8% patients.

CONCLUSION

The arthroscopy of the ankle with microfractures is safe, cheap and effective method in the treatment of osteochondral lesions.
