Ultrasonographic diagnosis of bone tumor of the knee and its clinical implication

Abstract

In order to evaluate the value of the ultrasonography in the diagnosis of tumor of the knee and its clinical implication, 67 patients with clinically suspected bone tumor of the knee were examined by ultrasound. The ultrasonographic characteristics of different bone tumors were studied and compared with the results of pathologic characters after operation. Ultrasonography can readily visualize the bony destruction and the pathologic change of the periosteum and the soft tissue related to bone tumor. Fifty-two cases of malignant bone tumors and 15 cases of giant cell tumors were diagnosed by ultrasonography. Pathologically, there were 54 cases of malignant bone tumor and 13 cases of giant cell tumor. It was concluded that ultrasonographic examination might be a useful method for the diagnoses of bone tumor of the knee and play an important role in guiding needle biopsy and electing operative method and approach.
