概括
前十字带重建 (ACLR) 的运动员在跑步时显示膝盖力和部补偿力减少. 在ACLR发生后,这种关节不对称性可能需要有针对性的临床随访.
科学领域:
- 生物力学 生物力学
- 整形外科手术 整形外科手术
- 运动医学 运动医学
背景情况:
- 过早的骨关节炎是前十字带重建 (ACLR) 后运动员的常见后果.
- 在ACLR后,膝关节关节接触力 (JCF) 减少与骨关节炎的发展有关.
- 在JCF中对邻近或对立关节的补偿性转移,以及它们对任务需求的依赖,仍然不清楚.
研究的目的:
- 在接受ACLR和匹配对照组的个人之间比较部,膝盖和脚JCF对称性.
- 调查ACLR后个体在行走和跑步任务之间是否存在补偿性JCF效应的差异.
主要方法:
- 招募了30名单边ACLR (2-7年手术后) 和30名匹配对照的参与者.
- 在行走和跑步期间,为部,膝盖和脚计算了JCF峰值和JCF冲动的四肢对称指数.
- 用于分析数据的差异 (组,活动) 的双因素分析.
主要成果:
- 患有ACLR的参与者在行走和跑步时表现出明显较低的峰值膝关节JCF和膝关节JCF冲动.
- 在峰值关节JCF中发现了群体和活动之间的显著相互作用,ACLR参与者在跑步时对涉及的四肢表现出更大的力量.
- 在小组之间或跨任务之间没有观察到脚JCF或地面反应力对称性指数的显著差异.
结论:
- 在ACLR运行2-7年后的个体表现出改变的JCF,在运行时膝盖力下降和部 ipsilateral 力量增加.
- 这些近端关节的适应,特别是在像跑步这样更高要求的活动中,表明需要临床关注.
- 在ACLR后的膝关节和部JCF不对称性可能需要针对性的临床策略和后续评估来缓解骨关节炎风险.

Knee Joint
1.8K
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...

Development of the Limb Synovial Joints
1.4K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Ankle Joint
1.6K
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...

Bones of the Lower Limb: Femur and Patella
2.5K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Bones of the Lower Limb: Tibia and Fibula
3.4K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Eccentric Axial Loading in a Plane of Symmetry
199
Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.
