Motion-Preserving Salvage for Failed Total Ankle Arthroplasty or Talar AVN: Outcomes of Combined Total Ankle Arthroplasty with Custom 3D-Printed Total Talus Replacement

This study investigates the outcomes of a motion-preserving salvage strategy, combining total ankle arthroplasty (TAA) with custom 3D-printed total talus replacement (TAA-TTR), for patients with talar component collapse or talar avascular necrosis (AVN). The authors found that TAA-TTR resulted in a manageable complication rate and facilitated rapid functional recovery, suggesting it as a viable alternative to traditional salvage methods that sacrifice motion. However, they emphasize the importance of careful patient selection to optimize outcomes.
