Clinical Diagnostic Value of Magnetic Resonance Imaging in Knee Joint Sports Injury

This article mainly analyzes the clinical effects of magnetic resonance diagnosis in knee meniscus injury. Patients with knee meniscus injury were taken as the research object. All patients used magnetic resonance examination and surgery and arthroscopy examination, and surgery and arthroscopy examination as the control parameters. The analysis used magnetic resonance diagnosis results and the classification of meniscus injury diagnosed by magnetic resonance and surgery and arthroscopy. The results showed that the sensitivity, specificity, and accuracy of conventional MR1 sequence diagnosis of medial meniscus injury were 86.3%, 95.6%, and 92.4%, respectively. The sensitivity, specificity and accuracy of conventional MRI in diagnosing lateral meniscus injury of the knee joint were 91.3%, 94.5%, and 92.5% respectively. The sensitivity of MRI to medial and lateral meniscus injury was (χ ² = 0.07, P > 0.77), There were no significant differences in specificity χ ² = 0.01, P > 0.77) and accuracy χ ² = 0.01, P > 0.77). The knee meniscus injury has a greater impact on patients. The diagnostic effect of magnetic resonance imaging is better and the diagnostic accuracy is higher. It can help clinical judgment and treatment. The effect is obvious and worthy of clinical promotion.
