title: Total Ankle Replacement Survival Rates Based on Kaplan-Meier Survival Analysis of National Joint Registry Data.
abstract: National joint registry data provides unique information about primary total ankle replacement (TAR) survival. We sought to recreate survival curves among published national joint registry data sets using the Kaplan-Meier estimator. Overall, 5152 primary and 591 TAR revisions were included over a 2- to 13-year period with prosthesis survival for all national joint registries of 0.94 at 2-years, 0.87 at 5-years and 0.81 at 10-years. National joint registry datasets should strive for completion of data presentation including revision definitions, modes and time of failure, and patients lost to follow-up or death for complete accuracy of the Kaplan-Meier estimator.
