QUESTIONS AND CORRECT ANSWERS
GRADED A+
● Flexion/Extension. Answer: Select the correct pairing below that
identifies an actual degree of freedom combination in the knee joint:
● Internal/ External. Answer: Select the correct pairing below that
identifies an actual degree of freedom combination in the knee joint:
● Varus/ Valgus. Answer: Select the correct pairing below that identifies
an actual degree of freedom combination in the knee joint:
● anterior/ posterior. Answer: Select the correct pairing below that
identifies an actual degree of freedom combination in the knee joint:
● Medial/ Lateral. Answer: Select the correct pairing below that
identifies an actual degree of freedom combination in the knee joint:
● Screw home, functional, deep flexion. Answer: The arcs of flexion in
the knee are:
, ● The center of the femoral head to the center of the ankle joint. Answer:
The mechanical axis of the lower extremity is determined by drawing a
straight line from:
● The transepicondylar axis of the femur combined with the longitudinal
axis of the tibia. Answer: When we refer to the "functional axes" of the
knee, we reference the combination of rotations around what two axes?
● The MCL and LCL. Answer: The flexion-extension axis closely
corresponds to the insertion points of what two ligamentous soft tissue
structures in the knee joint?
● The most prominent points of the medial and lateral epicondyles.
Answer: The "anatomical" (aka, "clinical") transepicondylar axis of the
of the knee is an imaginary line that connects:
● The medial epicondylar sulcus with the prominence of the lateral
epicondyle. Answer: The "surgical" epicondylar axis is an imaginary line
that connects:
● Medial. Answer: Which distal femoral condyle (medial or lateral) in
the knee joint has a sulcus?
● Perpendicular to the surgical transepicondylar axis. Answer:
Whiteside's Line is:
