Triathlon's full periphery locking rim, locking wire, and anti-rotation island have demonstrated
less ___ than other designs.
- micromotion
- aseptic loosening
- posterior overhang
- mid-flexion instability - CORRECT ANSWER-micromotion
True or false: regardless of tray size, the peg diameter on all triathlon tritanium baseplates is
7mm. However, the peg lengths rage in length from 7mm to 12mm depending on the size of the
baseplate - CORRECT ANSWER-true
the single radius design of triathlon allows for ___ required by the quadriceps to extend the
knee joint.
- less force
- more force
- equal force
- no force - CORRECT ANSWER-less force
the distal femur and proximal tibia create the ___ of the knee joint.
, - extension gap
- flexion gap
- mid-flexion gap
- none of the listen answers are correct - CORRECT ANSWER-extension gap
true or false: the tritanium foam thickness on the underside of the tritanium baseplate is
1.75mm thick - CORRECT ANSWER-false
When we refer to the "functional axes" of the knee, we reference the combination of rotations
around what two axes?
- the mechanical axis of the femur combined with the longitudinal axis of the tibia
- the mechanical axis of the femur combined with the transepicondylar axis of the femur
- the transepicondylar axis of the femur combined with the longitudinal axis of the tibia
- the transepicondylar axis of the femur combined with the anatomic axis of the femur -
CORRECT ANSWER-the transepicondylar axis of the femur combined with the longitudinal axis
of the tibia
Is the deep flexion arc of motion active or passive? - CORRECT ANSWER-passive
True or false: as the knee joint flexes thought the functional arc of motion as we walk, and the
tibia is lifted off the ground, the femur externally rotates with reference to the tibia. - CORRECT
ANSWER-true
Select the correct pairing below that identifies an actual degree of freedom combination in the
knee joint:
- distal / anterior
- extension / anterior
- external / proximal
