【 摘 要 】

Category:Ankle ArthritisIntroduction/Purpose:Background: In 2014, Daniels et al reported the largest prospective comparison of clinical outcomes for Ankle Fusion (AF) and Replacement (TAR). Outcomes were comparable at 5.5 years mean F/U but were not stratified for potentially important factors including ipsilateral:Intra-articular deformitySignificant foot deformityHindfoot arthritis (or prior fusion)These factors define the Type and complexity of end stage ankle arthritis (ESAA) as described by the COFAS Classification. Since the effect of COFAS Type on outcomes is unknown, it remains unknown if TAR or AF might outperform the other in specific Types of ESAA and therefore be preferentially indicated.Purpose:Determine if outcomes for TAR and AF:vary with COFAS Typeare different for ankles of the same COFAS Type.Methods:Prospective data from the COFAS multicenter database (3 sites, 5 surgeons) was used to compare outcomes in 890 consecutive non-randomized ankles with minimum 2 year F/U.
