CASE 80: Synovial Sarcoma Located in the Knee
- Hits: 215
A patient presented with swelling in the back of the knee. Physical examination and radiological tests revealed a soft tissue mass, and a needle biopsy revealed a soft tissue sarcoma. We performed surgery to remove the tumor with clean margins following radiotherapy after diagnosing the condition, and to close the resulting cavity with a gastrocnemius flap and skin graft.
Preoperative: MRI shows an irregularly bordered, heterogeneous mass located in the back of the knee, displacing the vascular and nerve bundle.
During the Operation: The clinical appearance before and after mass removal and the resulting cavity are shown.
During the operation: The image shows the gastrocnemius flap and skin graft being used to close the resulting gap.
