Summary
The Ilizarov ring fixator is a reliable method for knee arthrodesis after infected total knee arthroplasty removal. This technique achieved successful healing in most patients, avoiding further surgery.
Area of Science:
- Orthopedic surgery
- Infectious disease management in orthopedics
Context:
- Infection after total knee arthroplasty is a severe complication.
- Arthrodesis may be necessary to salvage the limb.
- The Ilizarov external fixator is a potential treatment option.
Purpose:
- To evaluate the outcomes of knee arthrodesis using the Ilizarov ring fixator in patients with infected total knee arthroplasty.
Summary:
- Eight patients underwent knee arthrodesis with the Ilizarov external fixator.
- Six of the eight arthrodeses healed successfully without further intervention.
- One patient experienced an above-knee amputation due to chronic infection; another died before follow-up.
Impact:
- The Ilizarov ring fixator demonstrates reliability for knee arthrodesis post-infected total knee arthroplasty.
- This method offers a viable solution for limb salvage in complex orthopedic cases.
