Learning objectives To provide a comprehensive overview of the role of different radiological techniques in the diagnostic workflow of osteoarthritis mentioning also the main differentials.
Read more Background Osteoarthritis is a degenerative multifactorial joint disease associated with a high rate of disability affecting 528 million people according to the WHO report of 2019. Patients suffer from pain, swelling, stiffness, and mobility impairment. Osteoarthritis is characterized by cartilage damage, synovitis, subchondral bone remodeling, and osteophytes which can be assessed through imaging.
Read more Findings and procedure details Imaging:Radiographs still  represent the initial imaging modality for diagnosing osteoarthritis due to the ability to assess joint space narrowing, osteophytes, as well as bone remodeling, articular malalignment, subchondral cyst, and sclerosis (Figure 1).Using radiographs, disease severity can be graded applying the Kellgren and Lawrence system (osteoarthritis is associated with a score ≥2) [1]:Grade 0: No radiographic features of osteoarthritisGrade 1: Doubtful joint space narrowing and possible osteophytic lippingGrade 2: Definite osteophytes and possible joint space narrowing;Grade 3: Multiple osteophytes, definite...
Read more Conclusion In the diagnostic workflow of osteoarthritis, radiologists should be aware of the role of each radiological technique and have a deep knowledge of the mainl differentials avoiding delayed diagnosis.
