Question

Using the concave-convex pattern of movement, which direction is the femur most likely to roll and glide when moving from standing to a sitting position?

A. Roll anterior and glide anterior
B. Roll posterior and glide anterior
C. Roll anterior and glide posterior
D. Roll posterior and glide posterior

Answer 1

In moving from standing to sitting, the femur rolls posteriorly and glides anteriorly at the knee joint, following the concave-convex pattern of knee movements.

Step-by-step explanation:

When moving from standing to a sitting position, the femur rolls posterior and glides anterior in relation to the tibia at the knee joint. This is due to the concave-convex pattern of movement where the convex femoral condyles articulate with the concave tibial condyles. As the knee flexes, the femur rolls in the opposite direction of the movement—posteriorly, while gliding in the same direction as the movement—anteriorly.
