Summary
Total talus replacement (TTR) can alleviate pain for talar collapse but carries risks. Surgeons must carefully consider potential complications like infection and instability for successful outcomes.
Area of Science:
- Orthopedic surgery
- Podiatric medicine
Background:
- Total talus replacement (TTR) is an emerging salvage procedure for talar collapse.
- A thorough evaluation of TTR-associated complications is necessary due to its increasing use.
Purpose of the Study:
- To review complications encountered in clinical practice and the literature following total talus replacement.
- To highlight potential adverse outcomes associated with TTR.
Main Methods:
- Literature review and patient case reporting.
- Analysis of complications including ligamentous instability, infection, and adjacent joint osteoarthritis.
Main Results:
- Total talus replacement offers potential pain reduction and range of motion preservation.
- Adverse outcomes, including severe complications, can occur after TTR.
Conclusions:
- TTR may be beneficial for select patients with end-stage talar collapse.
- Implant factors, patient selection, and demographics influence TTR outcomes and literature interpretation.
