Summary
Resection-arthrodesis is a viable surgical option for primary bone tumors around the knee, offering good functional outcomes despite potential local complications like infection and non-union.
Area of Science:
- Orthopedic Surgery
- Surgical Oncology
- Musculoskeletal Oncology
Background:
- Bone defects after primary bone tumor resection around the knee are typically reconstructed with allografts or prostheses.
- Resection-arthrodesis presents an alternative for specific patient groups, particularly younger individuals with financial constraints or limited allograft availability.
Purpose of the Study:
- To evaluate the outcomes and complications of resection-arthrodesis for primary bone tumors around the knee.
- To assess the functional results and long-term success of this surgical technique.
Main Methods:
- A retrospective study of 22 patients with primary bone tumors (13 giant cell tumors, 9 osteosarcomas) around the knee treated between 1990 and 2003.
- Mean follow-up duration of 6 years (range 1-13 years), with outcomes assessed using the Musculoskeletal Tumor Society grading system.
Main Results:
- Local complications included infection (36.4%), non-union (31.8%), and mal-union.
- Three patients with osteosarcoma died from lung metastasis; three required above-knee amputation.
- Of 14 patients evaluated, 79.8% achieved satisfactory functional outcomes.
Conclusions:
- Resection-arthrodesis is a feasible treatment for selected patients with primary bone tumors around the knee.
- Good functional outcomes are achievable, even with the occurrence of short-term local complications.
