Weight-bearing radiography in osteoarthritis of the knee. (2016) Clinical Orthopaedics and Related Research®. Classifications in Brief: Kellgren-Lawrence Classification of Osteoarthritis. Fontboté R C, Nemtala U F, Contreras O O, Guerrero R. Knee osteoarthritis diagnosis, treatment and associated factors of progression: part II. Radiographic Evaluation of Arthritis: Degenerative Joint Disease and Variations. Osteoarthritis of the Knee: Comparison of MR Imaging Findings with Radiographic Severity Measurements and Pain in Middle-Aged Women. Osteoarthritis of the Knee: Association Between Clinical Features and MR Imaging Findings. Subchondral bone marrow oedema and/or cystsĬartilaginous defects (partial or full-thickness) The following features are seen additionally on MRI 1,10:Įffusion and synovial thickening / synovitis The initial study of any patient with suspicion of knee osteoarthritis should include a Rosenberg view, a PA radiograph with weight-bearing and 45 degrees of flexion, which is more sensitive to detect joint space narrowing 5. Plain radiographs are the workhorse of imaging including follow-up, although there is a poor correlation between radiographic findings and clinical symptoms 1,2. Weight-bearing radiographs will demonstrate more joint space narrowing than non-weight-bearing radiographs, hence affecting the radiographic severity 7,8Īltered shape of the femoral condyles and tibial plateau Usually asymmetric, typically of the medial tibiofemoral compartment, and/or patellofemoral compartment 3 The hallmarks of knee osteoarthritis are the same for most other joints 6: The medial femorotibial joint compartment is more commonly affected and often more severe compared to the lateral 2. In the community, it is estimated to affect ~12.5% of patients >45 years 8. Knee OA is very common and is the most common joint disease in the elderly. Kellgren-Lawrence grade 2 or less on radiographsĪrthroscopic cartilage lesion and/or OA-related MRI findings such as subchondral bone marrow lesions and/or cartilage and meniscal degeneration The term early osteoarthritis of the knee has been proposed and has been defined as meeting three main criteria 9:
