Arthroscopic subtalar arthrodesis – results and complications

Abstract

Objective: The objective of this study is to evaluate the results and complications of the subtalar arthrodesis technique conducted via arthroscopy. Methods: Searches were run on PubMed/Medline and Google Scholar for publications dated from 2007 to 2020. Original articles were included that reported the results of at least one comparative postoperative scale. Methodological quality was assessed using the PRISMA tool. Union rate, complications, and the American Orthopedic Foot and Ankle Society (AOFAS) score were prioritized. Results: A total of 124 references were identified and, after application of the inclusion and exclusion criteria and the PRISMA tool, 9 articles were eligible. A total of 180 patients were analyzed, with mean postoperative follow-up of 18 months (± 6) and with before and after AOFAS scores varying from 44 to 79 with p<0.001, demonstrating statistical relevance with significant improvement of AOFAS scores during the postoperative period. Deformity correction, improvement of pain, and rates of union were good and there was clinical improvement according to postoperative AOFAS scores, with few complications. However, the heterogeneous nature of studies, with variations in techniques and samples, prevents generalization of the findings. Conclusion: The results of arthroscopic surgery for subtalar arthrodesis are good and rates of complications are low, but there are still few studies with high evidence levels that demonstrate the efficacy of the technique, although preliminary results are encouraging.
