[Knee replacement of the treatment of malignant tumor of the proximal tibia and early follow-up].
OBJECTIVE
To discuss the clinical effects of using rotating hinge prosthesis in treating primary malignant tumor of the proximal tibia.


METHODS
After the malignant tumor of the proximal tibia was extensively resected or radically resected, rotating hinge prosthesis replacement was performed for reconstruction, while neoadjuvant chemotherapy was used in treating the osteosarcoma.


RESULTS
The average follow-up period was 4.2 years. There was no local recurrence and metastasis in 22 patients, though there was recurrence in 8 patients. The MSTS functional scores of all different items 4 years after the operations were above 3, which showed the clinical results were satisfactory.


CONCLUSIONS
It is an efficacious method for the treatment of malignant tumor of the proximal tibia by using rotating hinge prosthesis. It has the advantage of early recovery of joint function.
