Registry Data Trends of Total Ankle Replacement Use

Total Ankle Replacement Survival Rates Based on Kaplan-Meier Survival Analysis of National Joint Registry Data

“…For example, analysis of the Salto Mobile prosthesis across national joint registries up to 2011 indicates it is has been embraced and is undergoing sustained growth. 5 The Salto Mobile prosthesis first appeared in the Norwegian Arthroplasty Register 16 in 2012, however, and was abruptly replaced by the fixed-bearing Salto Talaris and Salto Talaris XT total ankle prostheses (Tornier, Bloomington, Minnesota) in 2013. 22 The rationale for this abrupt conversion from the mobile to PE fixed-bearing version of the same TAR system, especially when the other TAR systems included in the registry have relatively consistent use over a much longer time period, is intriguing but unknown.…”

“…The BP was withdrawn from use in 2009 and the AES in 2010 for the reasons discussed previously. 5 The version of the STAR available for use in the United States is a single-coated titanium plasma spray on the metallic components. 4 This is an important consideration because the Norwegian Arthroplasty Register demonstrated a difference in survival between the hydroxyapatite single-coated and partially titanium-calcium phosphate double-coated version compared with the double-coated design that demonstrated better results specific to incidence of prosthetic loosening.…”

“…Additionally, 2 general Internet-based search engines, Google and Google Scholar, were used to search for additional national joint registry publications involving TAR based on a prior publication of this topic. 5 TAR survival was defined as retention of the prosthesis without revision, removal, or exchange of part of or the entire prosthesis. The national joint registries' specific definitions of revision were noted and are described in Table 1 for consistency, although slight variations were apparent between registries.…”

“…4 The implementation of national joint replacement registries worldwide would limit bias by providing large-scale prospective data collection and analysis of patient-related data and prosthetic component data and by including revision with explanation for failure as the primary outcome. 5 Currently, 33 national joint registries exist for all major orthopedic joints amenable to prosthetic implantation (http://www. arthroplastywatch.com/?page_id55; last accessed .…”

Rheumatoid Arthritis and Total Ankle Joint Replacement

“…Roukis and Prissel [16] performed an observational analysis of worldwide ankle replacement registry data comprising 13 different ankle replacement systems, involving 6 countries that had available data regarding ankle replacement performed between 2000 & 2011. The Mobility ankle replacement was the most frequently implanted replacement system worldwide (33%) with a significant increase in use since 2007.…”
