Category:Ankle Arthritis.Introduction/Purpose:Although recent studies have shown comparability of gait function following total ankle arthroplasty (TAA) and ankle arthrodesis, TAA is regarded to be functionally advantageous by preserving tibiotalar motion. However, it is unknown whether arthritic ankles with severe loss of sagittal plane motion are appropriate surgical candidates for arthroplasty. This study was undertaken to address the question: Is there a rationale for motion-preserving surgery in patients with little or no preoperative sagittal plane motion?Methods:A retrospective review of 76 patients who underwent isolated TAA with a minimum one-year follow-up, including patient demographics and pre and postoperative gait studies was conducted. Using a linear regression model, an effect size for total preoperative sagittal ROM was calculated, as well as effects of age, and patient demographics. Gait function was evaluated for postoperative improvement using multivariate analysis to determine the inf...
