Patient Expectation and Satisfaction as Measures of Operative Outcome in End-Stage Ankle Arthritis: A Prospective Cohort Study of Total Ankle Replacement Versus Ankle Fusion

摘要

Background: Current operative outcome scales are based on pain and function, such as the Ankle Osteoarthritis Scale (AOS). Outcomes based on patient expectation and satisfaction may be more useful. The purpose of this prospective cohort study was to evaluate associations between patient expectation, satisfaction, and outcome scores for ankle fusion and total ankle replacement (TAR).
