Talar avascular osteonecrosis (AVN) is a complication that has been very difficult to treat. This complication can lead to osseous collapse following a total ankle arthroplasty (TAA) which limits the viable treatment options even further. Total talus replacement (TTR) is a proposed treatment option in order to maintain function without sacrificing stability. We present a prospective case report on two patients receiving a custom unconstrained TTR after failed TAA with >3 years follow up. Both patients had improvements in their overall range of motion, AOFAS, VAS and SF-36 scores at short term follow up. Both patients returned to their daily activities without restrictions. Most recent radiographs demonstrate a return of hindfoot instability in case 1 while there is no increase in deformity in case 2. Therefore, a custom TTR seems to be a viable option for patients suffering from talar collapse after a TAA.
