The first generation of total ankle replacements were cemented, two-component, more or less constrained designs,
which in Sweden were abandoned in the mid 1990´s due to inferior results.
The second generation total ankle replacements (2-component and uncemented, allowing space for rotation within the mortise)
and the third generation (3- component and uncemented designs with a polyethylene meniscus, avoiding rotational strain)
have shown better results in the long term. The second generation prostheses were never introduced in Sweden but the first third
generation prosthesis was implanted in 1993.
The concept of reporting all ankle replacements to a national registry appeared 1997
and later that year a registry was implemented.
Since 2008 the database is administered by RC-syd National Registry Centre located in Lund (www.rcsyd.se).
The registry also includes ankle fusions and supramalleolar osteotomies.
