Image-guided percutaneous interventions for bone tumors around the knee

Both benign and malignant tumors, including metastases, commonly occur in the bones around the knee. During the past few decades, image-guided percutaneous treatments have proved effective for the management of osteoid osteoma as well as for palliation of painful bone metastases. The advent of interventional oncology has led to less invasive and less morbid treatment options when compared with surgery. Clinical indications have therefore been expanded to a variety of painful benign bone tumors beyond osteoid osteoma. In addition, bone metastases and bone sarcoma recurrence in selected patients can now be treated percutaneously with a curative intent. This article aims at providing a unique interdisciplinary perspective on image-guided percutaneous interventions for both benign and malignant bone tumors around the knee, including thermal ablation, intralesional injections, as well as bone consolidation techniques. The expanding range of clinical indications and future directions are herein discussed with an emphasis on the challenges encountered specific to this anatomic region.
