Value of X-ray Photography and Magnetic Resonance Imaging in the Diagnosis of Knee Degenerative Osteoarthropathy and the Evaluation of Arthropathy

Abstract

Abstract Purpose: this work was to explore the diagnostic value and lesion evaluation value of magnetic resonance imaging (MRI) and X-ray in knee joint degenerative osteoarthropathy. Methods: a total of 92 patients with knee degenerative osteoarthropathy who were admitted to our hospital from March 2021 to September 2022 were included in the study. They were randomly assigned into a control (Ctrl) group (n = 46) and an observation (Obs) group (n = 46) according to the random number table. X-ray films were taken in Ctrl group, and MRI images were taken in Obs group to compare their diagnostic accuracy and evaluation efficiency for arthropathy. Results: in terms of osseous structural lesions, the detection rates of the two methods were not greatly different (P > 0.05). For meniscal cartilage and peripheral soft tissues, the detection rate of MRI was obviously superior to that of X-ray. The diagnostic sensitivity (95.55%) was obviously higher than that of X-ray (86.04%), and the diagnostic coincidence rate (93.47%) was obviously higher than that of X-ray (80.43%). For the first-stage joint lesions, the detection rates of MRI (55% and 11/20) were drastically superior to those of X-ray (35% and 7/20), while for the second-stage joint lesions, the detection rates of MRI (66.66% and 14/21) were higher than those of X-ray (45.4% and 10/21) (P< 0.05). Conclusion: the diagnostic coincidence rate and detection rate of knee degenerative osteoarthropathy with MRI were superior to those with plain X-ray film, which is helpful for the early diagnosis of the disease and worthy of clinical promotion and adoption.
