Retrospective analysis of 110 ankle prostheses.

This study presents results of 110 third-generation ankle arthroplasties performed at four principle centers with a follow-up of 3 years. Prostheses used were the Star, the LCS, and the Ramses. Indications were represented by arthrosis (72 cases, almost all of which were post-traumatic) and rheumatoid arthritis (27 cases). There were 63 women and 47 men, with an average age of 56 years. Results were generally good, especially in relation to pain, which improved in 70% of cases. Function results were less favorable, particularly in relation to dorsal flexion, which did not improve after operation. Walking perimeter increased in more than 40% of cases. In the "Conclusion," we discuss indications for ankle arthroplasty instead of arthrodesis, as of the latter are not always good, and complications are frequent.
