The Current Trend of Total Ankle Replacement

Abstract

Total ankle replacement (TAR) was introduced for end-stage arthritis of the ankle joint in the 1970s. TAR is becoming the modality of choice and offers better mobility, improved gait, and reduces the development of subsequent subtalar joint arthritis when compared with ankle arthrodesis. To maintain the longest function of ankle replacements, the de‐ sign of the prosthesis should allow for smooth and continuous interaction and normal gait. Improved operative techniques, the surgeon’s experience, as well as appropriate pa‐ tient selection can anticipate better outcomes. Deformities of the ankle and foot should be corrected before TAR is performed. Despite the functional limitations following the revi‐ sion of TAR, the revision still offers a cost-effective alternative to ankle arthrodesis. The decision to treat with TAR depends on the surgeon’s technique, as well as on the patient’s condition.
