Yang TC, Tzeng YH, Wang CS, et al. - This research was sought to assess the surgical outcome in terms of radiographic measurements, functional outcomes, and complications following arthroscopic ankle arthrodesis (AAA) in patients 60 years of age or older, and to compare the results of patients with mildly deformed ankle with those of patients with severely deformed ankle. Researchers retrospectively examined patients who had undergone AAA with three cannulated screws between January 2008 and December 2017 and followed postoperatively for at least 24 months. They compared demographic data and radiographic and functional outcomes between patients with coronal deformity of less than 15 degrees (Group I) and those with a deformity equal to or greater than 15 degrees (Group II). This study enrolled a sum of 41 patients with a mean age of 70.6 years (Group I, n = 26; Group II, n = 15) and mean follow-up was 51.4 months. Evidence showed that AAA was found to be a reliable technique for end-stage ankle arthritis in patients 60 years of age or older resulting in a high union rate, encouraging radiographic and functional outcomes, and a low complication rate, even in cases with severe preoperative deformity. It was reported that arthroscopic intra-articular malleolar osteotomy was a beneficial method for correcting severe coronal deformity in our series.
