Total Ankle Replacement is a recognised treatment
for end-stage ankle arthritis and an alternative to
arthrodesis. This study reviews a single centre series
of prospectively collected outcome measures to
determine whether the Mobility performs better than
the Scandinavian ankle replacement. The primary
outcome measure was the survivorship. Secondary
outcome measures consisted of complications and
international scoring systems.
147 Scandinavian and 162 Mobility ankle replacements
were reviewed at a mean follow up of 12.4 and 7.7
years respectively. The revision rate, which included
liner exchange, component exchange or removal of
implant was at 7 years 12.3% (18) for Scandinavian
and 5.2% (8) for Mobility. The complication rate was
16.5% (22) for Scandinavian compared to 9.9 % (15)
for Mobility.
The results of our unit compare favourably with
previous published studies. In this study the Mobility
has been shown to have more favourable results at 7
years compared to the Scandinavian.
