摘要
目的综述外侧盘状半月板(discoid lateral meniscus,DLM)损伤患者术后下肢生物力学特征研究进展。方法检索国内外DLM相关研究文献,对DLM损伤患者术后膝关节运动生物力学、胫股关节应力分布、下肢力线以及髌股关节变化特征进行总结。结果DLM损伤患者手术治疗后下肢生物力学特征出现不同程度改变。其中,膝关节运动生物力学特征显著改善,但仍存在伸展缺陷等问题。胫股关节的峰值应力随残余半月板体积增大而减小,且变化程度与残余半月板体积密切相关;术中保留较多的半月板体积,尤其是前角体积,有助于减少应力集中。术后下肢力线会出现外翻偏移,且术中切除半月板越多,术后下肢力线改变越大。术后髌股关节则存在软骨退变、位置和角度变化等情况。结论DLM损伤术后下肢生物力学特征发生改变,与手术方式及术后康复方案选择密切相关。但下肢多关节生物力学特征改变及其机制、以及研究样本个体差异仍有待进一步研究明确。
Objective To review the research progress on the lower limb biomechanical characteristics of patients with discoid lateral meniscus(DLM)injury after surgery.Methods By searching relevant domestic and international research literature on DLM,the postoperative characteristics of knee joint movement biomechanics,tibiofemoral joint stress distribution,lower extremity force line,and patellofemoral joint changes in patients with DLM injury were summarized.Results Surgical treatment can lead to varying degrees of changes in the lower limb biomechanical characteristics of patients with DLM injury.Specifically,the kinematic biomechanics of the knee joint can significantly improve,but there are still problems such as extension deficits in the affected knee joint.The peak stress of the tibiofemoral joint decreases with the increase of the residual meniscus volume,and the degree of change is closely related to the residual meniscus volume.Preserving a larger volume of the meniscus,especially the anterior horn volume,helps to reduce stress concentration.The lower extremity force line will deviate outward after surgery,and the more meniscus is removed during surgery,the greater the change in the lower extremity force line after surgery.There are conditions such as cartilage degeneration,position and angle changes in the patellofemoral joint after surgery.Conclusion The changes in the lower limb biomechanical characteristics after DLM injury are closely related to the choice of surgical methods and rehabilitation programs.However,the mechanisms of biomechanical changes in multiple lower limb joints and individual differences still need to be further studied and clarified.
