Knee osteoarthritis (OA) is a commonly encountered disorder with increasing prevalence and economic burden. Although joint replacement is the gold standard treatment in more advanced cases, a variety of other treatments can be performed for mild to moderate OA cases, patients on a surgical waiting lists, unsuitable surgical candidates, or those not wanting surgery. Knowledge of image-guided therapies for knee OA is essential for musculoskeletal radiologist to offer appropriate treatments for patients with this common and disabling disorder.

Educational Goals / Teaching Points
Describe the pathophysiology of knee OA. Review the available imaging modalities to diagnose knee OA. Understand the role of image-guided intervention for knee OA.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Knee OA is produced by multiple overlapping and complex interaction of multiple factors including repetitive trauma/stress, inflammatory and metabolic factors. The amount of inflammation and synovitis associated with OA is quite variable but may have potential implications for treatment options.

Image-guided intervention is an important aspect in treatment of OA. Radiologists and specifically musculoskeletal radiologists play critical role in this disease and awareness of these interventions, their technique, expected response and complications is essential to provide appropriate care for this disabling disorder.
