Fixed Versus Mobile Bearings in Total Ankle Arthroplasty
Much controversy exists in the general arthroplasty literature regarding bearing options (Heisel et al., J Bone Joint Surg Am 85:1366–79, 2003). One particularly robust facet of this debate has revolved around the choice between fixed-bearing designs and mobile-bearing designs. Although the majority of this discussion over the past few decades has focused on bearing choices in total knee arthroplasty, the controversy remains very active within the total ankle replacement (TAR) domain as well. One of the primary reasons for the ongoing debate is that both mobile- and fixed-bearing concepts have noteworthy theoretical advantages and disadvantages. At the same time, both designs are capable of yielding excellent patient outcomes as well as potential failures.
