Ankle Arthrodesis: Indications, Outcomes, and Patient Satisfaction.

Abstract

Background Osteoarthritis of the ankle, which has a prevalence of 3.4% in the general population and affects 70% of candidates post-traumatically, is less common than hip or knee arthritis. Despite the recent progress in ankle arthroplasty surgery, ankle arthrodesis is still considered the gold-standard treatment for severe osteoarthritis of the ankle joint and can achieve impressive improvements in pain and function in the majority of patients. Our objective is to assess the clinical and functional outcomes of ankle arthrodesis, postoperative complications, and patient satisfaction. Methodology This was a descriptive cross-sectional study that took place at Future Hospital in Khartoum, Sudan, from July 2015 to July 2022. Our institute performed 102 ankle fusion surgeries; 14 patients were excluded from the study because they did not show up for their follow-up visit, meaning 88 candidates were included. Two cannulated screws (6.5 mm) were used for ankle fixation in all patients. The outcome was assessed two years after surgery. The American Orthopaedic Foot and Ankle Society (AOFAS) score was used to assess ankle function before surgery and two years after the procedure. Postoperative complications and patient satisfaction were reported. The primary researcher collected data through direct interviews. Result The mean age of the study participants was 52.2 years, with 36.4% being between 40 and 50 years of age. The study consisted of 43 women and 45 men. The male-to-female ratio was almost 1:1. In 56.8% of candidates, the right ankle was involved. The overall rate of complications was 11.4%. Concerning patient satisfaction, 75% of the patients were fully satisfied. Moreover, significant correlations were found between the mean postoperative AOFAS score and age group, diabetes mellitus, complications, and patient satisfaction. Conclusion Ankle arthrodesis was demonstrated to be an excellent surgical method for reducing pain and enhancing ankle joint function. The most frequent complications were delayed wound healing, infection, and non-union. The functional outcome and patient satisfaction of this procedure were statistically high; patients with a higher functional score had higher levels of satisfaction. In contrast, diabetic and elderly patients had higher rates of complications.
