Abstract
Limb salvage is a key goal of tumor management around the knee, with surgical, medical,
and radiologic treatment options. Primary bone and soft tissue sarcomas are optimally
treated in specialist tertiary centers; however, metastatic disease is encountered
in all aspects of radiologic practice, with overlap in the management strategies.
Both specialist and generalist radiologists therefore need to be familiar with the
expected normal appearances following these therapies and be able to recognize potential
complications. This review article describes the techniques available for imaging
the knee following treatment of bone and soft tissue tumors, with particular reference
to artifact reduction. The therapeutic options for managing bone and soft tissue lesion
are discussed, with emphasis on imaging appearances. Surgical, medical, and radiologic
treatments are described. Complications and their imaging appearances are reviewed
including local recurrence of tumor, infection, complications related to metallic
implants, postradiation changes, and amputation. Normal imaging appearances and complications
following radiologic treatment (namely radiofrequency ablation) of bone and soft tissue
tumors are presented.
