Interventional articular and para-articular knee procedures.

Area of Science:

• Orthopedic Surgery
• Radiology
• Sports Medicine

Background:

• The knee is a frequent site for interventional procedures, particularly due to sport-related injuries affecting soft tissues.
• Image-guided interventions are crucial for diagnosing and treating various knee pathologies.

Purpose of the Study:

• To detail image-guided interventional issues specific to the knee.
• To discuss technical aspects, indications, and considerations for procedures involving knee soft tissues, tumors, and lesions.

Main Methods:

• Review of image-guided techniques for knee interventions.
• Discussion of procedures including arthrography, biopsies, and ablative therapies (cryoablation, ultrasound, microwave, radiofrequency ablation).
• Exploration of interventions for osteochondral lesions and Brodie's abscess.

Main Results:

• Image guidance is essential for interventions in knee soft tissues, biopsies of tumors, and various ablation techniques.
• Radiofrequency ablation is the most common ablation method used around the knee.
• Newer, unproven interventions for specific knee conditions are also mentioned.

Conclusions:

• Image-guided interventions play a vital role in managing a wide spectrum of knee conditions, from soft tissue injuries to tumors and lesions.
• Technical considerations and therapeutic applications of these image-guided methods are critical for successful outcomes.
• Ongoing advancements offer potential for future knee interventions.
