CASE 29: Osteosarcoma located in the knee (distal femur)
- Hits: 268
Our young male patient underwent extraarticular knee resection and distal femur tumor prosthesis reconstruction following chemotherapy for osteosarcoma located on the distal femur and extending to the knee joint.
Before the surgery: X-ray shows irregularity in the distal femur, and MRI shows effusion in the joint accompanied by a large tumor tissue in the same location.

During the Surgery: The image shows the patella incision, the resulting gap after resection, and soft tissue coverage.

During the Surgery: Clinical and fluoroscopy images of the removed knee joint containing the tumor.

Post-Surgery: The X-ray shows the distal femur tumor prosthesis implanted after resection.
