The Agility Total Ankle Prosthesis (DePuy) is a semi-constrained, fixed-bearing prosthesis that was designed in 1984 and currently has 510(k) clearance from the FDA [14] (Figure 11.11). In the United States, it is the most commonly used TAR prosthesis and has more than 20 years of clinical experience [55].
