まとめ
膝関節整形手術 (TKA) の後の関節線傾き (JLO) の回復は,階段の交渉中に前面の平面関節を変化させなかった. これはJLOの回復がTKA後の患者の満足度に影響を与えないことを示唆している.
科学分野:
- 整形外科
- バイオメカニクス
- 手術 の 結果
背景:
- 膝関節整形手術 (TKA) の不満率は15%です
- 関節線傾き (JLO) はTKAの結果に影響を与える潜在的な要因です.
研究 の 目的:
- TKA患者で階段の交渉中にJLOの回復が下肢前面の関節の瞬間に影響を与えるかどうかを調査する.
- TKA患者に対するJLO回復の生体力学的影響を決定する.
主な方法:
- 3D運動と地面反応力は,階段の交渉中に30人の回復していないと22人の回復したJLO TKA患者で記録されました.
- フロント平面の足首,膝,股関節の瞬間は,Visual 3Dソフトウェアを使用して計算されました.
主要な成果:
- JLOの復元は,階段の交渉中に前面の平面の関節を変化させなかった.
- 復元されたJLOグループと復元されていないJLOグループは,対称なモメントプロファイルを示した.
- グループ間の有意な生体力学的差異は見つかりませんでした.
結論:
- TKA患者では,前面の平面関節の瞬間に影響を与えないようです.
- JLOの回復は,TKA後の患者の満足度の格差の主な要因ではないかもしれません.
- TKAの回復における外科技術とインプラント設計の役割をさらに研究する必要があります.

Ankle Joint
1.8K
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...

Knee Joint
2.2K
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...

Stress on an Oblique Plane
697
Understanding stress on an oblique plane under axial loading is pivotal in material mechanics. This analysis offers insight into a material's durability and strength, which is crucial for civil engineering and structural design. Axial loading refers to force application along the material's central axis, causing compression or elongation and leading to normal stress. Normal stress occurs when a force acts perpendicularly to the material's area, resulting in compressive or tensile...

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.

Bones of the Lower Limb: Femur and Patella
2.9K
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...

Movement Joints in Buildings
170
Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
