Summary
Total ankle arthroplasty (TAA) has higher reoperation and infection rates than ankle arthrodesis. While TAA preserves motion, ankle fusion may offer better long-term outcomes for end-stage ankle arthritis.
Area of Science:
- Orthopedic surgery
- Biomechanical engineering
Background:
- End-stage ankle arthritis presents a significant clinical challenge.
- Treatment options include total ankle arthroplasty (TAA) and ankle arthrodesis (fusion).
- Patient-specific factors influence the optimal choice between TAA and ankle fusion.
Purpose of the Study:
- To compare reoperation rates, infection rates, survival rates, and range of motion between TAA and ankle arthrodesis.
- To identify factors influencing the decision-making process for treating end-stage ankle arthritis.
Main Methods:
- Comparative analysis of existing literature and clinical data.
- Review of reoperation rates, infection incidence, and implant survival.
- Assessment of functional outcomes, specifically arc of motion.
Main Results:
- Total ankle arthroplasty (TAA) demonstrates higher reoperation rates compared to ankle arthrodesis.
- Infection rates for primary TAAs range from 1.4% to 2.4%.
- TAA survival is approximately 75%-90% at 10 years, while ankle arthrodesis maintains motion through the talonavicular joint.
Conclusions:
- Both TAA and ankle arthrodesis are viable for end-stage ankle arthritis.
- Ankle arthrodesis may be favored due to lower reoperation and infection risks.
- Treatment selection requires careful consideration of individual patient characteristics and goals.
