Summary
Limb salvage surgery for high-grade proximal tibia bone tumors showed poor functional outcomes. Reconstruction challenges, including extensor mechanism repair and endoprosthetic use, led to limited joint mobility and extension power.
Area of Science:
- Orthopedic Surgery
- Surgical Oncology
- Musculoskeletal Oncology
Background:
- High-grade malignant bone tumors of the proximal tibia present significant treatment challenges.
- Limb salvage surgery aims to preserve limb function while eradicating the tumor.
Purpose of the Study:
- To evaluate the outcomes of various limb salvage techniques for proximal tibia malignant bone tumors.
- To describe a two-stage knee joint reconstruction method.
Main Methods:
- Retrospective analysis of 12 patients with high-grade proximal tibia malignant bone tumors (9 osteosarcomas, 3 malignant fibrous histiocytomas).
- Surgical interventions included muscle flaps, extensor mechanism reconstruction, and endoprosthetic insertion in most cases.
- One patient underwent arthrodesis.
Main Results:
- Poor functional results were observed in several cases.
- Common complications included loss of joint movement and failure to regain extension power.
- A two-stage knee joint reconstruction approach was employed.
Conclusions:
- Limb salvage for proximal tibia malignant bone tumors, despite surgical advancements, can yield suboptimal functional outcomes.
- Challenges in reconstructing the extensor mechanism and knee joint require innovative solutions.
- Further research into optimizing functional recovery after these complex reconstructions is warranted.
