概括
膝关节冠状平面对齐 (CPAK) 现型在膝关节骨关节炎进展期间保持一致. 这种一致性允许基于个体膝盖表型的个性化手术规划.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 生物机械工程 生物机械工程
背景情况:
- 膝关节骨关节炎 (OA) 是一种退行性关节疾病,其特征是软骨分解和结构变化.
- 膝盖冠状平面对齐 (CPAK) 描述了前面平面下肢的整体对齐,这可能会影响OA的发展和进展.
- 在OA进展的背景下了解CPAK表型对于有效的治疗策略至关重要.
研究的目的:
- 在经历了8年的膝关节骨关节炎 (OA) 进展的患者中调查膝关节冠状元平面对齐 (CPAK) 现型的稳定性.
- 为了确定特定对齐参数的变化,如算术-膝-脚角 (aHKA) 和关节线斜率 (JLO),是否与OA进展期间CPAK表型的变化相关.
主要方法:
- 长度研究涉及248名患者 (79名男性,169名女性),初步评估于2012年,随访于2020年.
- 膝关节OA的进展定义为从Kellgren-Lawrence (KL) 级0-2向KL级3或4的进展.
- 调整参数的测量:aHKA,JLO,关节-膝盖-脚角 (HKA),横向远距离大腿角 (LDFA),中位近腰角 (MPTA) 和关节直线收角 (JLCA).
主要成果:
- 在2012年至2020年期间,CPAK表型的分布保持一致.
- 在OA进展过程中观察到MPTA,aHKA,JLO,JLCA和HKA的显著变化.
- 没有发现侧边远股骨角 (LDFA) 发生显著变化.
结论:
- 膝盖冠状平面对齐 (CPAK) 分类系统是宪法对齐的可靠预测指标,即使膝关节关节炎的进展.
- CPAK表型保持稳定,使外科医生能够根据个体患者的表型来定制手术前对齐计划,以获得最佳的结果.

Knee Joint
1.9K
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...

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.

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...

Eccentric Axial Loading in a Plane of Symmetry

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.

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...
