背景：由于异常生物力学应力导致内侧半月板挤出（MME）增加，导致膝关节骨关节炎（OA）进展。步行过程中的MME评估是检测半月板动态变化的关键方法，结合运动分析可以更深入地了解MME增加的机制。目的：基于MME增加与生物力学因素的相关性，验证MME动态评估与运动分析系统结合的可行性。方法：本研究分析了23例轻度至中度膝关节OA患者的23个膝关节。步行时通过超声评估内侧半月板。MME的增加计算为行走期间最小和最大MME之间的差值。三维运动分析系统与超声同步，然后，生物力学因素，如膝关节力矩和地面反作用力evaluated.Results：的中外侧和垂直分量的地面反作用力和膝关节内收力矩的波形相似的那些在MME的基础上的高互相关系数（>0.8）。MME的增加与膝关节内收力矩的峰值显著相关（r = 0.54，P = 0.0073），但与地面反力的中、外侧和垂直分量无相关性。研究结果表明，膝关节内收力矩与行走过程中MME的增加相关，并表明MME动态评估结合运动分析系统(c)2022 Elsevier B.V.保留所有权利。
Background: An increase in medial meniscus extrusion (MME) due to abnormal biomechanical stress leads to knee osteoarthritis (OA) progression. MME evaluation during walking is a key method of detecting dynamic changes in the meniscus, and in combination with motion analysis, can provide a deeper understanding of the mechanisms involved in the increase of MME.Objective: To validate the feasibility of MME dynamic evaluation in combination with a motion analysis system based on the correlation between the increase in MME and biomechanical factors.Methods: Twenty-three knees from 23 patients with mild to moderate knee OA were analysed in this study. The medial meniscus during walking was evaluated by ultrasound. The increase in MME was calculated as the difference between the minimum and maximum MME during walking. A three-dimensional motion analysis system was synchronised with the ultrasound and then, biomechanical factors such as knee moment and ground reaction force were evaluated.Results: The wave patterns of the mediolateral and vertical components of ground reaction forces and knee adduction moment were similar to those in the MME based on a high cross-correlation coefficient (>0.8). The increase in MME was significantly correlated with the peak value of the knee adduction moment (r = 0.54, P = 0.0073) but not with the mediolateral and vertical components of the ground reaction force.Conclusion: The findings show that knee adduction moment is correlated with an increase in MME during walking and indicates the validity and feasibility of the dynamic evaluation of MME in combination with a motion analysis system.(c) 2022 Elsevier B.V.
