まとめ
前半帯 (ACL) 損傷における前半帯外解 (ATS) は,前半帯転移,損傷から手術までのより長い時間,および逆側膝の過剰伸縮によって予測されます. これらの要因は手術前の安定性と 移植の成功に影響します
科学分野:
- 整形 科 と スポーツ 医学
- 膝 の 手術
- バイオメカニクス
背景:
- 膝の伸縮部における前側帯 (ATS) は,前側帯 (ACL) の損傷でよく見られる.
- 術前のATSは,術後の前部安定性に悪影響を及ぼし,ACL再建後の早期の移植不全のリスクを高めます.
研究 の 目的:
- 前十字帯 (ACL) 損傷の患者における手術前の前側帯外解 (ATS) と関連した重要な要因を特定し,調査する.
主な方法:
- 主要なACL再建を施した191人の患者を対象とした横断研究が実施された.
- 手術前側線 X線写真でATSが評価され,陽性ATSは側対側差 (SSD) > 3. 6mmで定義される.
- ロジスティック回帰分析では,年齢,性別,傷害から手術までの時間,後部足の傾き,超伸縮角度,前部足の転移 (ATT) を含む予測要因が評価されました.
主要な成果:
- 陽性なATSは32人の患者で観察された.
- 陽性ATSの予測因子には,より大きな前頭葉転移 (ATT) (OR: 1. 27),慢性性 (手術までの傷害> 6ヶ月) (OR: 2. 89) および逆側膝の超伸縮角度 (OR: 1. 10) が含まれていた.
- 半月板の破裂と術前のATSとの間に有意な関連性は見つかりませんでした.
結論:
- 術前前膝の緩解性 (ATT),ACL欠乏症の慢性化,対側膝の過剰伸縮は,術前ATSの有意な予測要因である.
- これらの要因を理解することは 術前評価と ACL 損傷した膝の手術計画の最適化に不可欠です
- レベル3の証拠は,これらの発見を支持します.

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...

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...

Muscles that Move the Leg
2.8K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

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...
