Survival of 308 total ankle replacement. A 1-14 years
follow-up.

Background:
As total ankle replacement (TAR) becomes a white spread solution
to degenerative ankle disease it is important to know the results after TAR.
Purpose / Aim of Study:
The aim of this study is to describe the failure pat-
tern and the survival rate of the STAR TAR.
Materials and Methods:
It is a single center prospective study of 308 STAR
TAR. 231 with osteoarthrosis (OA) and 77 had rheumatoid arthritis (RA) were
done in a period from 1998 to the 1. of June 2012. Failure was defined as failure
of one or more prosthetic component.
Findings / Results:
Twenty-five with OA and 17 with RA were failures. Fifteen
OA and 4 RA were late failures where only the polyethylene component was
broken or worn. Seven OA and 3 RA patients had a revision. Ten RA and 7 OA
had an arthrodesis. One, 5 and 10 Year survival rate survival rate for OA was
0.97, 0,90 and 0,77 respectively. One, 5 and 10 year survival rate for RA was
0,90, 0,84 and 0,75.
Conclusions:
There is a relatively high early failure rate especially for the RA pa-
tients the late failures are dominated by failure of the polyethylene component.
Despite the relatively high failure rate 223(97%) of 231 OA TAR is still in place
and 67(87%) of 77 RA TAR is still in place.
