Evaluation of the new defined EFAS score (European foot and ankle society score) in relation to already established functional scores (FFI, MOXFQ) after cartilage reconstructive therapy (AMIC®) for osteochondral lesion of the talus.

BACKGROUND: In 2011, the European Foot and Ankle Society developed a Score (EFAS Score) to generate a standardized questionnaire for several European languages. The aim of this study is to analyse how the newly defined score correlates with already established function scores. METHODS: This study is a monocentric prospective study. The questionnaires were completed at least 12 months postoperatively at the same time point. All patients had undergone surgery with the Autologous Matrix-Induced Chondrogenesis® procedure for osteochondral lesions of the talus. RESULTS: A total of 69 patients (33 women, 36 men) participated in the study. The EFAS Score correlates very strongly with the Manchester-Oxford Foot Questionnaire (MOXFQ) and strongly with the Foot Function Index (FFI). CONCLUSION: This study shows that the EFAS Score correlates significantly with the FFI and the MOXFQ. The EFAS seems to be a more patient-friendly alternative due to fewer questions and response choices.
