To investigate application of the Codamotion 2CX1 three-dimensional dynamic joint motion capture system to analyze the kinematic characteristics of patients with different degrees of meniscus injury.
From December 2020 to June 2022, 135 patients with meniscus injury and recruited normal people were collected, including 82 males and 53 females, aged 14 to 29 years old, with disease duration of 1 to 3 months. Combined with clinical symptoms and MRI examination, the diagnosis of meniscus injury was confirmed, and the patients were divided into stages, including 37 cases of grade 0(normal), 30 cases of gradeⅠ, 33 cases of gradeⅡ, 35 cases of grade Ⅲ according to Stoller grading standard. Subjects in each group were tested walking by using Codamotion 2CX1 three-dimensional dynamic joint motion capture system. Quantitative indexes of walking and kinematics were collected, including knee flexion and extension, internal and external rotation and internal and external turning, and their kinematics were analyzed.
In the distribution of knee flexion/extension, there were significant differences in maximum knee flexion, minimum knee extension and knee flexion and extension range among 4 groups(<0.05). In the distribution of internal/external rotation of knee joint, there were significant differences in the range of internal rotation and rotation of knee joint among 4 groups(<0.05). In the distribution of internal/external turning of knee joint, there were significant differences in the range of internal and external turning of knee joint among 4 groups(<0.05). The clinical stage progression was positively correlated with the range of motion of knee extension, external rotation, internal and external turning and turning range(<0.05). It was negatively correlated with knee flexion, internal rotation, flexion extension and rotation range(<0.05). The internal and external rotation angles of knee joint could be used as independent factors influencing the clinical stage of meniscus injury (=0.006, 0.019<0.05).
The knee movement of patients with meniscus injury has obvious changes, and the changes are different under different clinical stages. Gait analysis provides a reliable basis for the kinematic analysis of meniscus injury, helps to better understand the kinematic indexes of joints, and provides a reliable auxiliary diagnosis and treatment plan, which provides a new direction for the follow-up medical research.
探讨Codamotion 2CX1三维动态关节运动捕捉系统在分析不同程度半月板损伤患者运动学特征中的应用。
收集2020年12月至2022年6月期间135例半月板损伤患者及招募的正常人，其中男性82例，女性53例，年龄14至29岁，病程1至3个月。结合临床症状及MRI检查确诊半月板损伤，并根据Stoller分级标准将患者分为0级（正常）37例、Ⅰ级30例、Ⅱ级33例、Ⅲ级35例。使用Codamotion 2CX1三维动态关节运动捕捉系统对每组受试者进行步行测试。收集步行及运动学的定量指标，包括膝关节屈伸、内外旋及内外翻，并对其运动学进行分析。
在膝关节屈伸分布方面，4组间最大屈膝、最小伸膝及屈伸范围差异有统计学意义（<0.05）。在膝关节内外旋分布方面，4组间内旋范围及膝关节旋转差异有统计学意义（<0.05）。在膝关节内外翻分布方面，4组间膝关节内外翻范围差异有统计学意义（<0.05）。临床分期进展与膝关节伸、外旋、内外翻及翻转范围呈正相关（<0.05）。与屈膝、内旋、屈伸及旋转范围呈负相关（<0.05）。膝关节内外旋转角度可作为影响半月板损伤临床分期的独立因素（=0.006，0.019<0.05）。
半月板损伤患者膝关节运动有明显改变，且在不同临床分期变化不同。步态分析为半月板损伤的运动学分析提供了可靠依据，有助于更好地了解关节运动学指标，提供可靠的辅助诊断及治疗方案，为后续医学研究提供了新方向。
