Imaging of osteoarthritis

Area of Science:

• Orthopedics
• Radiology
• Rheumatology

Background:

• Osteoarthritis (OA) is the most common joint disease affecting the elderly population.
• Currently, no definitive cure exists for OA, making early diagnosis and monitoring crucial.
• Accurate assessment of synovial joint structures is vital for OA management.

Purpose of the Study:

• To review the roles and limitations of various imaging modalities in the diagnosis, prognosis, and follow-up of knee osteoarthritis.
• To discuss recent research developments and evidence in OA imaging published since 2008.

Main Methods:

• Review of conventional radiography and magnetic resonance (MR) imaging.
• Consideration of ultrasonography, nuclear medicine, computed tomography (CT), and CT/MR arthrography.
• Emphasis on knee OA and literature published post-2008.

Main Results:

• Conventional radiography and MR imaging are key modalities for evaluating knee OA.
• Other techniques like ultrasonography and CT arthrography offer complementary information.
• Recent advancements have improved the diagnostic and prognostic capabilities of OA imaging.

Conclusions:

• Imaging plays a critical role in the clinical practice and research of knee OA.
• A comprehensive understanding of different imaging modalities is essential for effective OA management.
• Ongoing research continues to refine imaging techniques for better OA outcomes.
