Summary
This case report details managing a complex knee osteoarthritis case after multiple femur fracture surgeries. Computer-navigated total knee arthroplasty successfully addressed the condition while preserving existing hardware.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Complex periprosthetic femur fractures (Vancouver C type) following total hip arthroplasty present significant surgical challenges.
- Previous osteosynthesis using distal femoral locking compression plates (LCP) can compromise bone quality and increase refracture risk.
Observation:
- A 60-year-old female patient with a history of multiple femur fracture repairs developed severe knee osteoarthritis.
- The patient's femur bone quality was compromised due to prior procedures, raising concerns about hardware removal and refracture risk.
Findings:
- A computer-navigated total knee arthroplasty was performed, retaining the existing distal femoral LCP plate.
- This approach avoided intramedullary guiding, ensured precise joint alignment, and mitigated refracture risks.
Implications:
- Computer-navigated total knee arthroplasty offers a viable solution for complex cases with compromised bone stock and retained hardware.
- This technique facilitates accurate component placement and optimal joint function in challenging revision scenarios.
