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, withvariations 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 stillfew studies with high evidence levels that demonstrate the efficacy of the technique, although preliminary results are encouraging.

Summary
Degenerative injuries of the subtalar joint have multiple etiologies, such as primary osteoarthrosis, posttraumatic arthritis, inflammatory arthropathy, congenital pathologies, or acquired deformities. When conservative treatment is unsuccessful, arthrodesis can relieve pain and improve functional status. Primarily when walking on rough ground, and instability are both common, leading to loss of function and restriction of activities[4]. Pain may be caused by subtalar and/or calcaneocuboid arthritis, widening of the lateral wall, causing impact on the fibular tendons, malalignment of the hindfoot, loss of heel height and inclination of the talus (causing ankle pain and reducing impulse strength), in addi tion to damage to the fat pad of the heel and/or injury to sensory nerves of the hindfoot[5]
