Arthrose de la cheville et de la sous-talienne

Most of the time, tibiotalar osteoarthritis and subtalar osteoarthritis are post traumatic. Ankle osteoarthritis is usually well tolerated except after surgical malleolar misalignment, causing misrotation of talus and articular incongruency. Arthrodesis is considered the standard treatment for end-stage post-traumatic osteoarthritis of the ankle, with good results provided special attention has been paid to good per operative adjustment, and provided the technique has been adapted to the anatomic lesion, more particularly to a potential need for extension to posterior subtalar joint, supposed to be the major point of pre-operative diagnosis. The ankle arthroplastic surgery (third generation) is promising but it needs to be validated by the analysis of surgical series with an important follow-up concerning components fixation. Isolated subtalar osteoarthritis needs subtalar arthrodesis after careful analysis of the local anatomic changes and the impact on the whole foot, in order to adapt the technique.
