At present, there few studies on the kinematic features of lateral discoid meniscus injury. In this study, a motion capture system was used to investigate the motion characteristics of knees with lateral discoid meniscus after injury, and the differences between the knees with lateral meniscus and intact knees were compared. Fourteen patients diagnosed with unilateral lateral discoid meniscus injury, fourteen patients diagnosed with unilateral lateral meniscus injury, and fourteen normal subjects with healthy knees were recruited and grouped. Through kinematic gait analysis, it was found that the subjects in the two groups with meniscus injuries exhibited significantly smaller ranges of rotation and translation than those with healthy knees on the sagittal, coronal, and horizontal planes, but not in proximal-distal translation. Maximum lateral tibial translation and maximum internal tibial rotation in the knees with lateral discoid meniscus injury were significantly decreased compared to those with lateral meniscus injury. The results show that the kinematic features of knees with lateral discoid meniscus injury are statistically different than those of healthy knees and knees with lateral meniscus injury. This study provides an important reference for the dynamic function of knees with lateral discoid meniscus injury.

步行时椎间盘半月板损伤的患者的运动学特征。

目前，关于盘状外侧半月板损伤的运动学特征的研究很少。在这项研究中，使用运动捕捉系统来研究具有外侧盘状半月板损伤的膝盖的运动特征，并比较具有外侧半月板的膝盖和完整膝盖之间的差异。招募了十四名被诊断为单侧外侧半月板半月板损伤的患者，十四名被诊断为单侧半月板半月板损伤的患者以及十四名健康膝关节的正常受试者。通过运动步态分析，发现半月板损伤的两组受试者在矢状，冠状和水平面上的旋转和平移范围均比健康膝盖的受试者小得多，但近端-远侧平移却没有。与外侧半月板损伤相比，膝间盘状半月板损伤的最大外侧胫骨平移和最大胫骨内旋转度明显降低。结果表明，侧圆盘状半月板损伤的膝关节的运动学特征与健康膝关节和半月板半月板损伤的膝盖在运动学上有统计学差异。该研究为膝间盘状半月板损伤的膝关节动力功能提供重要参考。结果表明，侧圆盘状半月板损伤的膝关节的运动学特征与健康膝关节和半月板半月板损伤的膝盖的运动学特征在统计学上是不同的。该研究为膝间盘状半月板损伤的膝关节动力功能提供重要参考。结果表明，侧圆盘状半月板损伤的膝关节的运动学特征与健康膝关节和半月板半月板损伤的膝盖在运动学上有统计学差异。该研究为膝间盘状半月板损伤的膝关节动力功能提供重要参考。
