[Total ankle arthroplasty : update]

Total ankle prosthesis is increasingly recognized in the management of severe osteoarthritis and has established itself as a valid alternative to arthrodesis. However, this procedure remains delicate, indications must be targeted, and the complex surgical technique requires specific expertise from the surgeon. In recent years, ankle arthroplasty has undergone a major expansion, with improvements in design and surgical techniques. New technologies have also emerged, offering tailor-made planning and instrumentation possibilities. The influence of these techniques on long-term results has yet to be demonstrated, but benefits such as reduced operating time and improved surgical accuracy are interesting. The purpose of this article is to provide an update on ankle prosthesis in the treatment of ankle osteoarthritis.
