Abstract:
Objective:This study focuses on the changes of the knee meniscus injury imaging to evaluate the clinical efficacy and feasibility of MRI in its diagnosis.Methods: A total of 110 cases of patients with knee meniscus injury in our hospital were selected and were randomly divided into two groups. The observation group was carried out MRI while the control group did routine CT examination. All were confirmed by surgery or arthroscopy. Evaluating the diagnostic value of MRI on the knee meniscus injury according to the comparative analysis based on examined results for the two groups.Results:In selecting a total of 55 patients, the knee meniscal injuries were unilateral, in which there were 51 medial meniscus injuries and 40 lateral meniscuses. There were 28 cases of the level 1 injuries, 43 cases of the secondary injury and 20 cases of the level 3 injuries. Therefore, there were no differences between the observation group and the surgery or arthroscopy examination(t=0.416,t=0.323,t=0.121;P>0.05). The analysis of the differences was statistically significant between the control group and the surgery or arthroscopy examination(Z=-2.491,P<0.05). Conclusion: MRI can determine the extent of damage by morphological and signal changes of the knee meniscus. It can provide a very reliable basis for clinical diagnosis, which has high diagnostic value.
