Open Chain and Closed Chain Kinematics of the Tibiofemoral Joint Flashcards
1
Q
In the Open Chain during Knee Extension, What motion occurs at the Tibia?
A
Lateral/External Rotation of The Tiba
2
Q
In the Open Chain during Knee Flexion (unlocking), What motion occurs at the Tibia?
A
Medial/Internal Rotation of the Tibia
3
Q
In the Closed Chain during Knee Extension, What motion occurs at the Femur?
A
Medial/Internal Rotation of the Femur
4
Q
In the Closed Chain during Knee Flexion (unlocking), What motion occurs at the Femur?
A
Lateral/External Rotation of the Femur
5
Q
Why does the screw home mechanism occur?
A
Due to the Lateral Femoral Condyle being _Flatter_
- Therefore, it is unable to _extend as far distally _as the medial condyle
