Introduction: Ankle arthrodesis is a common procedure for fusion of the distal part of the tibia and the talus. The indications vary from arthritis (post-traumatic), inflammatory conditions, degenerative conditions and avascular necrosis of the talus to extreme deformities of the ankle. Ankle arthrodesis, which accounts for more than 85% of ankle surgeries. This article is intended to study functional outcome of ankle arthrodesis in ankle arthropathy. Material and Methods: This article contains a prospective study of 20 patients with a mean age of 44.8 years, males – 15 and females -5, who underwent ankle arthrodesis for the diagnosis of traumatic arthritis (18 patients), charcot ankle arthropathy (1 patient) and rheumatoid arthritis (1 patient), with a follow up period of 12 months. Results: Out of 20 patients, 95% showed radiological union at follow up period of 12 months and 17 patients had good to excellent functional outcome using AOFAS score. Mean AOFAS ankle hindfoot scale at 12 months was 72.85 with standard deviation of 12.04. Conclusion: For patients with ankle arthritis the gold standard salvage procedure is ankle arthrodesis, as the procedure effectively relieved the pain of patients and corrected the deformity, hence helped them to return to the Activities of Daily Living with minimal complications and near complete functional recovery subjectively.
