Whilst evidence shows good clinical results after surgery, little is known of the long\u2010term survival of ankle replacements and the need for ankle revision. Using more recent implant data and long\u2010term data, there is now opportunity to examine at a population\u2010level the survival rate for ankle implants, to examine between\u2010country differences in ankle revision surgery, and to compare temporal trends in revision rates between countries.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Four national joint registries from Australia, New Zealand, Norway and Sweden provided the necessary data on revision outcome following primary ankle replacement, for various periods of observation \u2013 the earliest starting in 1993 up to the end of 2019. Data were either acquired from published, online annual reports or were provided from direct contact with the joint registries. The key information extracted were Kaplan\u2010Meier estimates to plot survival probability curves following primary ankle replacement.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The survival rates varied between countries. At 2 years, across all registries, survival rates all exceeded 0.9 (range 0.91 to 0.97). The variation widened at 5\u2009years (range 0.80 to 0.91), at 10\u2009years (range 0.66 to 0.84) and further at 15\u2010years follow\u2010up (0.56 to 0.78). At each time point, implant survival was greater in Australia and New Zealand with lower rates in Sweden and Norway.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>We observed variation in primary ankle replacement survival rates across these national registries, although even after 5\u2009years, these population derived data show an 80% revision free survival. These data raise a number of hypotheses concerning the reasons for between\u2010country differences in revision\u2010free survival which will require access to primary data for
