Total ankle arthroplasty is becoming the definitive treatment for end-stage, symptomatic arthritis of the tibiotalar joint. More sophisticated designs, stronger materials, improved surgical technique, and broader indications have led to an increased use. This educational exhibit will: 1. Review the current concepts of ankle replacement including various designs and modern surgical techniques. 2. Explain and illustrate the expected imaging appearances. 3. Demonstrate complications, and explain how such failures occur.

1. Types and prosthetic designs of ankle replacement 2. Current surgical techniques 3. Radiologic assessment 4. Complications a. Infection, b. Loosening c. Polyethylene wear d. Osteolysis, e. Periprosthetic fractures f. Component fractures g. Hypertrophic ossification h. Dislocation
