摘要/Abstract

摘要： 探讨MRI显像定量评价在盘状半月板体育运动损伤中的诊断价值。选取113例疑似盘状半月板体育运动损伤患者作为研究对象，根据膝关节镜检查结果，分为完整组（27例）、变性组（61例）、撕裂组（25例），均行MRI显像检查，分析盘状半月板损伤情况。结果显示，完整组、变性组、撕裂组外侧盘状半月板体部宽度（WDLM）、WDLM/股骨外髁宽度（WLFC）、游离缘高度/体部高度（HF/HM）呈逐渐升高趋势，关节囊缘高度（HP）、HP/HM呈逐渐下降趋势（P<0.05）；WDLM/WLFC、HF/HM联合诊断盘状半月板运动损伤与损伤类型的AUC大于各参数单独诊断；且WDLM、HF、WDLM/WLFC、HF/HM与膝关节软骨损伤呈正相关，HP、HP/HM与膝关节软骨损伤呈负相关（P<0.05）。MRI显像定量检查对盘状半月板运动损伤及损伤类型具有良好诊断价值，且均与膝关节软骨损伤显著相关，能为临床诊治提供依据。

Abstract: This paper investigated the diagnostic value of MRI quantitative evaluation in discoid meniscus sports injuries. 113 patients with suspected discoid meniscus sports injury were selected and divided into intact group (27 cases), degeneration group (61 cases), and tear group (25 cases) according to the results of knee arthroscopy. All patients underwent MRI imaging to examine the discoid injuries of the lateral meniscus, the results showed that the lateral discoid meniscus body width (WDLM), WDLM/lateral femoral condyle width (WLFC), free border height (HF)/body height in the intact group, the degeneration group, and the tear group (HM) showed a gradually increasing trend, while the joint capsule edge height (HP) and HP/HM showed a gradually decreasing trend (P<0.05). AUC of WDLM/WLFC, HF/HM combined diagnosis of discoid meniscus sports injury and injury type was greater than that of each parameter alone. WDLM, HF, WDLM/WLFC, HF/HM were positively correlated with knee cartilage damage, and HP, HP/HM were negatively correlated with knee cartilage damage (P<0.05). It is suggested that MRI imaging quantitative examination has good diagnostic value for discoid meniscus sports injury and injury type, and both of them are significantly related to knee cartilage injury, which can provide a basis for clinical diagnosis and treatment.
