Summary
Infection after tibial tubercle osteotomy can cause severe complications. A novel technique using a medial gastrocnemius flap successfully reconstructed the extensor mechanism, eradicating infection and restoring knee function.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Management
- Reconstructive Surgery
Background:
- Osteotomy of the tibial tubercle can lead to infection, nonunion, and chronic osteomyelitis.
- Radical debridement may necessitate resection of the tibial tuberosity, disrupting the knee's extensor mechanism.
- Literature review revealed no documented successful treatments for this specific complication.
Observation:
- A 28-year-old female patient presented with post-osteotomy infection and extensor mechanism disruption.
- Surgical intervention involved resection of the sequestrated tibial tuberosity and sinus tract.
- Reconstruction of the extensor mechanism was performed using a medial gastrocnemius flap.
Findings:
- The one-stage procedure successfully eradicated the infection.
- Excellent knee function was restored post-reconstruction.
- The presented technique demonstrated a positive 5-year outcome.
Implications:
- This case report introduces a viable surgical solution for a rare and challenging complication.
- The medial gastrocnemius flap offers a promising method for extensor mechanism reconstruction after tibial tuberosity resection.
- This approach may improve outcomes for patients suffering from severe post-osteotomy infections.
