Subtalar bone-block distraction arthrodesis using structural autograft carries the risk of donor site morbidity. Recent reports suggest that structural allograft may be an attractive alternative to structural autograft in subtalar arthrodesis. This prospective study analyzes subtalar distraction arthrodesis using interpositional structural allograft. ⋯ Level IV, prospective case series.

Fresh osteochondral total ankle allograft transplantation has been reported in the literature with survival rates between 50% and 92% at 1- to 12-years followup. The goal of this study was to present the results of total ankle allografts from another institution. ⋯ This is the largest series of osteochondral total ankle allograft transplants reported in the literature to date. There is an extremely high rate of failure associated with this procedure, and we currently consider it only rarely in patients who are too young for ankle replacement, have excellent range of motion, low body mass index, normal radiographic alignment, and who refuse arthrodesis.
