Comparative Analysis of Magnetic Resonance Imaging and X-ray Examination on Knee Degenerative Osteoarthrosis

Objective: To compare the diagnostic effect of magnetic resonance imaging (MRI) and X-ray in degenerative osteoarthritis of knee joint. Methods: 107 patients with degenerative osteoarthrosis of the knee were selected as study subjects. They were divided into study group (53 cases) and control group (54 cases) according to different diagnostic methods. The study group underwent MRI examination for diagnosis, and the control group underwent X-ray examination for diagnosis. The diagnostic criteria of arthroscopic surgery were used as the gold standard to compare the diagnostic accuracy of patients with knee degenerative osteoarthrosis. Result: There was no significant difference in the detection rate of joint space stenosis and bone hyperplasia between the two groups (P > 0.05). Compared with the control group, the positive rate of synovial thickening, soft tissue swelling and meniscus degeneration was higher in the study group, and the difference was statistically significant (P < 0.05). Discussion: The progression of knee degenerative osteoarthrosis is very slow, and the clinical symptoms are not specific and inconspicuous. Especially in the early stage, knee cartilage injury and degeneration are not obvious. X-ray examination is used to diagnose the misdiagnosis. The rate is relatively high, and MRI, as a non-invasive examination method, has the advantages of high tissue resolution, multiazimuth imaging and multi-parameter imaging, which can clearly show the knee meniscus, articular cartilage, bone, ligament and other soft tissue injuries. The diagnosis is remarkable. Conclusion: The application of MRI in the diagnosis of degenerative osteoarthrosis of the knee is significant, which can further improve the diagnostic detection rate, and it is worthy of promotion and application in the diagnosis.
