FAQs
1. What is the locking mechanism of the knee joint movement?
The knee joint features a “screw-home mechanism,” which provides stability during full extension. In the final degrees of extension, the tibia externally rotates relative to the femur, effectively “locking” the joint. This locked position allows for prolonged weight-bearing with minimal muscular effort. To initiate flexion, the popliteus muscle “unlocks” the knee by internally rotating the tibia, permitting movement.
2. What is a disarticulation of the knee?
Knee disarticulation refers to an amputation performed through the knee joint, separating the femur from the tibia without cutting through bone. This procedure preserves the full length of the femur, which can enhance prosthetic fitting and function.
3. What is the difference between single-axis and polycentric knees?
Single-axis prosthetic knees operate like a simple hinge, allowing flexion and extension around one axis. They are durable and lightweight but may offer limited stability. Polycentric knees have multiple rotational axes, providing a more natural gait and improved stability, especially beneficial for users with longer residual limbs or those requiring greater control.
