膝关节内侧半月板突出与后根部损伤相关性的MRI分析
Association between knee joint medial meniscus extrusion and posterior root tears:Magnetic resonance imaging analysis
摘要
Abstract
BACKGROUND:Meniscal root damage is an important reason for meniscus extrusion. In recent years, there are many reports on the relationship between meniscus root injury and meniscus extrusion at abroad, but it is rare at home. OBJECTIVE:To investigate the correlation between knee medial meniscus extrusion and the medial meniscus posterior root tears. METHODS:A retrospective analysis of the MRI and arthroscopic findings of 84 patients with knee medial meniscus extrusion signs was conducted. Medial meniscus extrusion≥ 3 mm or length of medial meniscus extrusion/maximum diameter of meniscus extrusion ≥10%was defined as serious extrusion. The chi-square test analysis was used to analyze the correlation between posterior root tears and the medial meniscus extrusion. RESULTS AND CONCLUSION:MRI measurement results of medial meniscus extrusion (length of medial meniscus extrusion ≥ 3 mm or length of medial meniscus extrusion/maximum diameter of meniscus extrusion≥ 10%) was significantly related with the arthroscopic findings of posterior root tears (P<0.05) with the odds ratio and 95%confidence intervals of 25.04 (3.07-204.44) and 6.96 (1.38-35.19) respectively. The medial meniscus serious extrusion is closely related to posterior root tears of the medial meniscus, which is a significant feature of the meniscus posterior root tears.关键词
