Abstract

Background: Osteoarthritis (OA) is a widely prevalent disease worldwide and is a major public health problem that primarily affects the elderly.The present study was undertaken to define the radiographic findings of osteoarthritis (OA) of knee joint using Kellgren-Lawrence scores and to define cartilage abnormalities on magnetic resonance (MR) imaging. Subjects and Methods: Present study was conducted on 50 patients presenting with knee pain and clinical suspicion of osteoarthritis. Antero-posterior radiographs of the knee were obtained in a weight-bearing extended position by using a standard radiographic technique. All radiographs were assigned scores by using the Kellgren-Lawrence scoring system.Cartilages alterations on MRI were assigned grades as follows: grade 0, normal; grade I, internal signal intensity alteration only; grade IIA, defect of cartilage of less than 50%; grade IIB, defect of cartilage of 50%–99%; grade IIIA, 100% defect of cartilage with no bone ulceration; or grade IIIB, 100% defect of cartilage with subjacent bone ulceration. Radiographic and MR imaging findings were compiled as per performa and subjected to analysis using appropriate statistical tests. Results: Among 26 patients of grade 0 K-L score, 6, 4, 6, 4, 4 and 2 patients had grade 0, grade 1, grade 2A, grade 2B, grade 3A and grade 3B Cartilage abnormality (On MRI) respectively. Among 8 patients of grade 1 K-L score, 2, 2, 2 and 2 patients had grade 0, grade 2A, grade 2B and grade 3A Cartilage abnormality (On MRI) respectively. Among 14 patients of grade 2 K-L score, 1, 4, 4 and 5 patients had grade 2A, 2B, 3A and grade 3B Cartilage abnormality (On MRI) respectively. Among 2 patients of grade 3 K-L score, both of these had grade 3B Cartilage abnormality (On MRI). Conclusion: MRI plays an important role in imaging the bony and soft tissues of knee as a whole organ, thereby helping in better management and outcome of the disease.
