概括
一个深度中间侧带 (dMCL) 损伤本身对膝盖不稳定性影响很小. 然而,结合深层MCL和部分表面MCL (psMCL) 的损伤显著增加了中间旋转不稳定性 (AMRI) 和旋旋转 (VR).
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 运动医学 运动医学
背景情况:
- 中间附带带 (MCL) 损伤,包括深层 (dMCL) 和表面 (sMCL) 部分,与中间旋转不稳定性 (AMRI) 有关.
- 部分表面MCL (psMCL) 损伤 (通常与dMCL损伤同时发生) 对AMRI的具体影响尚不清楚.
研究的目的:
- 确定孤立的dMCL损伤与联合的dMCL和psMCL损伤对膝关节松的影响.
主要方法:
- 人类尸体膝盖在各种条件下使用机器人模拟器进行了测试,包括前十字带 (ACL) 截断.
- 动力学分析测量了在不同膝盖曲角度的骨运动,骨旋转 (VR) 和中侧旋转 (AMR).
- 对dMCL和psMCL的顺序切割评估了它们对膝盖稳定性的单独和联合影响.
主要成果:
- 组合的dMCL和psMCL损伤显著增加了所有曲角度的外旋转和VR.
- 在ACL完好无损的膝盖中观察到AMR显著增加,这是联合伤害后的结果.
- 孤立的dMCL损伤对AMR的影响很小,对VR没有影响,而ACL对于控制中介转化至关重要.
结论:
- 一个孤立的dMCL损伤可能会导致AMRI的轻微增加,但不会显著影响VR.
- 联合dMCL和psMCL损伤导致AMRI和VR的显着增加.
- 当AMRI和VR在特定的屈曲角度上升时,对联合dMCL和psMCL损伤的临床怀疑是合理的.

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
