To compare survival outcomes of revision ankle arthrodesis (RAA) and revision total ankle arthroplasty (RTAA) following failed primary total ankle arthroplasty (TAA) and explore associated clinical and radiographic factors.
Key Findings:
Revision rates for TAA are significant, with RAA and RTAA showing varied survival outcomes.
Patient-related factors such as BMI, age, and sex influence outcomes.
Implant-related factors, including the presence of periarticular cysts, affect revision success.
Interpretation:
The study highlights the complexity of revision surgeries following failed TAA, emphasizing the need for tailored approaches based on individual patient and implant factors.
Limitations:
Retrospective design may introduce bias.
Limited follow-up duration for some cases.
Potential confounding factors not fully accounted for.
Conclusion:
Understanding the factors influencing outcomes in RAA and RTAA can guide clinical decision-making and improve patient management following failed TAA.
