概括
膝关节骨关节炎 (OA) 的关节结构与步态变化有关. 身体质量指数 (BMI) 在OA患者的步态中似乎比结构性病理更有影响力.
科学领域:
- 整形外科 整形外科 整形外科
- 生物医学工程 生物医学工程
- 放射学 放射学是一门学科.
背景情况:
- 膝关节骨关节炎 (OA) 是一种退行性关节疾病,影响全球数百万人.
- 膝盖骨关节炎患者的步行异常很常见,影响了他们的行动能力和生活质量.
- 了解结构性关节变化和步态之间的关系对于有效的OA管理至关重要.
研究的目的:
- 调查膝关节关节结构异常与膝关节OA患者的步态参数之间的关联.
- 为了确定与独特的步态模式相关的特定结构特征.
主要方法:
- 在IMI-APPROACH研究中招募了297名膝关节骨质炎患者.
- 使用GaitSmart®收集的步态数据,并通过X射线图 (KIDA) 和MRI (qMRI/MOAKS) 评估膝关节关节结构.
- 使用主要成分分析 (PCA) 进行步态参数和线性回归,以将结构/人口因素与步态组件联系起来.
主要成果:
- 确定了两个步行组件:上腿 (步行速度,步伐持续时间,部/大腿ROM) 和下腿 (小腿/膝盖ROM).
- 在非ROA患者中,年龄,BMI,骨密度,角和性别影响了下腿行走 (R2=0.24).
- 在ROA患者中,BMI,骨质细胞,阴茎挤出和性别影响下腿行走 (R2=0.18);BMI和性别也影响上腿行走 (R2=0.12).
结论:
- 结构性膝关节OA病理与步态变化有显著的关联.
- 身体质量指数 (BMI) 可能在步态障碍中起到更为关键的作用,而不是仅仅是结构变化.
- 这些发现突显了OA症状 (步态) 和关节结构之间的重要联系,为潜在的治疗点提供了信息.

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...

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...

Structural Classification of Joints
3.4K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
