Though the indications for total ankle replacement are controversial, it has been proposed as an alternative to arthrodesis. It is designed to preserve a functional range of motion and does not necessitate a long period of immobilization in a cast.
From 1980 to 1985 we replaced ten ankles in seven patients with rheumatoid arthritis. The average follow-up time was 19 months.
There was relief of pain and improvements in walking distance. But the gains in range of motion were poor.
