まとめ
膝関節の安定性や怪我のリスクは,主観的な関節緩解性テストや客観的な生体力学的評価によって予測できません. したがって,主観的な評価に基づいた運動プログラムは,科学的に健全ではありません.
科学分野:
- 整形外科 整形外科 整形外科
- スポーツ医学 スポーツ医学
- バイオメカニクス バイオメカニクス
背景:
- 膝関節の安定性と膝の怪我の発生率の関係については,依然として議論の対象となっている.
- 関節のゆるさ (緊迫性または緩解性) の主観的な評価は,運動の処方箋の基礎として提案されています.
研究 の 目的:
- 大学サッカー選手の膝関節の安定性と膝の怪我との関係を調査する.
- 主観的な関節松性評価が,膝の安定性の客観的な生体力学的測定値と相関するかどうかを判断する.
主な方法:
- 膝関節の安定性のバイオメカニカル研究は,1969年から1971年の間に401人の大学サッカー選手を対象に実施されました.
- 72人の大学サッカー選手に対して,関節軟弱性テストを実施した.
- 怪我のデータを収集し,プレーヤーの関節軟弱性分類に関連して分析しました.
主要な成果:
- 膝関節の怪我の43件のうち,19件は"緩い関節"の選手で,24件は"緊密な関節"の選手で発生しました.
- ジョイント・ラキシティー・テストに失敗した大学サッカー選手の分布は,プロ選手の分布と異なっていた.
- 主観的な関節松動性テストと客観的な生体力学的膝関節筋の安定性評価の間には有意な関係が見つかりませんでした.
結論:
- 主観的な関節の緩やかさや客観的な生体力学的評価に基づいて膝の怪我を予測することは実現不可能です.
- 膝の怪我の予防のための運動プログラムは,関節の緩やかさの主観的な評価のみに依存すべきではありません.

Bones of the Lower Limb: Femur and Patella
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 neck...
Knee Joint
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 group...

Ankle Joint
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
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 to...
