Image-guided percutaneous interventions for bone tumors around the knee

Area of Science:

• Orthopedic oncology
• Interventional radiology
• Minimally invasive procedures

Background:

• Bone tumors, both benign and malignant (including metastases), frequently affect the knee region.
• Historically, surgery was the primary treatment, often involving significant morbidity.
• Image-guided percutaneous treatments have emerged as effective alternatives over recent decades.

Purpose of the Study:

• To provide an interdisciplinary overview of image-guided percutaneous interventions for bone tumors around the knee.
• To discuss the expanding clinical indications for these minimally invasive techniques.
• To highlight challenges and future directions in treating bone tumors in this specific anatomical area.

Main Methods:

• Review of image-guided percutaneous interventions for bone tumors around the knee.
• Discussion of techniques including thermal ablation, intralesional injections, and bone consolidation.
• Emphasis on interventional oncology principles.

Main Results:

• Percutaneous treatments are effective for osteoid osteoma and palliation of bone metastases.
• Indications have expanded to include other painful benign bone tumors.
• Selected cases of bone metastases and sarcoma recurrence can be treated with curative intent percutaneously.

Conclusions:

• Image-guided percutaneous interventions represent a less invasive and less morbid approach to managing bone tumors around the knee.
• These techniques offer palliative and, in select cases, curative treatment options.
• Continued research and development are crucial for addressing the challenges specific to this region.
