Long-term results of total ankle replacement.

The results are reported of 19 total ankle replacements in 18 patients with rheumatoid or other inflammatory arthritis. After a mean follow-up period of 54.4 months (minimum, 24 months), three arthroplasties had failed, all because of loosening. Although all of the remaining patients were improved in terms of pain and function, there was radiographic evidence of loosening in a further eight patients. Indications for the operation are discussed.
