Summary
Knee arthrodesis can be challenging after infected knee replacement. A hybrid Ilizarov fixator with debridement successfully achieved fusion in two difficult cases.
Area of Science:
- Orthopedic surgery
- Infectious disease
Background:
- Knee arthrodesis is a salvage procedure for infected total knee arthroplasties, aiming for limb stability and infection eradication at the cost of motion.
- Challenges include poor bone stock, persistent infection, compromised soft tissues, and patient comorbidities.
Observation:
- Two cases of failed knee arthrodesis following periprosthetic infection were reported.
- Both patients had significant challenges complicating fusion.
Findings:
- Successful knee fusion was achieved in both cases using open debridement.
- A hybrid advanced Ilizarov fixator was employed to facilitate the fusion process.
Implications:
- This approach offers a viable solution for achieving knee fusion in complex infected total knee arthroplasty cases.
- The hybrid Ilizarov fixator technique demonstrates potential for successful limb salvage in challenging scenarios.
