Supramalleolar Osteotomies for Ankle Osteoarthritis: Clinical and Radiological Outcomes
Main Article Content
Abstract
Materials and Methods: Retrospective, observational, and descriptive study on patients who underwent SMOT for ankle osteoarthritis between January 2010 and July 2017. The patients’ clinical records were analyzed.
Results: We included 13 patients who underwent SMOT, 8 patients with valgus (61.5%) and 5 (38.5%) with varus rearfoot and ankle misalignment. The mean varus VAS score decreased from 9 ± 0.45 to 3 ± 1 postoperatively (p <0.05) and, in valgus deformities, from a mean 7.88 ± 0.35 to 2.15 ±1.64 postoperatively (p <0.05). The mean AOFAS score changed from 32.8 ± 16.2 to 82.1 ± 13.6 postoperatively in the varus deformity group (p <0.05) and from 31 ± 17.3 preoperatively to 93.1 ± 6.20 postoperatively in the valgus deformity group (p <0.05). Twelve patients (92.3%) achieved radiographic union in an average time of 10.4 weeks.
Conclusion: Supramalleolar osteotomy as a treatment for asymmetric ankle osteoarthritis is a predictable technique with very good clinical andradiological outcomes in the short and medium term.
