2024 Questions and Correct Answers
Agraded
Studies have consistently shown that Triathlon and the Single Radius
provide: -ANSWER-Stability, Satisfaction, and Survivorship
Most motion of the knee occurs in: -ANSWER-Active Flexion
Looking at the knee in sagittal plan through the transepicondylar axis,
the femur has a single center of rotation similar to a: -ANSWER-Circle
Single Radius is designed to restore the knee's single center of
rotation during active flexion. This allow for constant ". " tension and ".
" in flexion -ANSWER-Ligament / Stability
The single radius rotation is designed to: -ANSWER-All of the above
Triathlon's smooth-rotating single radius offers the potential to require
". "% less quad force. -ANSWER-57%
When we refer to the PF offset, we refer to: -ANSWER-The distance
between the patella and the pivot point of the femoral condyles.
Triathlon is designed to improve the functionality of the extensor
mechanism by providing a ". " PF offset than multi-radius designs. -
ANSWER-Longer
The lateral collateral ligament inserts onto: -ANSWER-The fibular
head
The quadriceps muscle group includes: -ANSWER-Rectus femoris,
vastus lateralis, vastus medialis, and vastus intermedius
,The Single Radius feature on the Triathlon femoral component exists
from: -ANSWER-10 degrees to 110 degrees
The Triathlon FlexRod bends to avoid making a distal femoral
resection in ". " due to a patient's anterior femoral bow. -ANSWER-
Extension
Triathlon's shortened and flared posterior condyles facilitate the ". " of
the soft tissues to enable ". " without excessive slope. -ANSWER-
Relaxation / Deep Flexion
The rotary arc on the Triathlon CR tibial insert allows for ". "
internal/external rotation and reduced contact stresses. -ANSWER-
None of the answers are correct
Pre-TKA, the patella tracks ". " on the femur as the knee extends -
ANSWER-Laterally
The Triathlon PS cam and post are designed to engage at ". " degrees
of ". " -ANSWER-45 / Flexion
The primary function of the PCL is to: -ANSWER-Prevent posterior
translation of the tibia on the femur
Triathlon's Anatomic Patellofemoral Track was designed with a
deepened trochlear groove to help: -ANSWER-All of the answers are
correct
The 7 degree anterior flange on the Triathlon femoral component is
designed to: -ANSWER-Intraoperatively downsize the femoral
component while avoiding the incidence of notching the anterior
femur.
When we refer to Triathlon as being an "anthropometrically based"
design, we mean that: -ANSWER-The design incorporated a variable
aspect ratio to adequately fit the female anatomy while still
accommodating larger male patients.
, The Triathlon tray geometry in the transverse plane (looking down on
the implant) is: -ANSWER-Symmetric
In a study by Wernecke, a tibial tray with an asymmetric geometry had
a higher rate of ". " and ". " overhang compared to symmetrical
designs like Triathlon. -ANSWER-Posterolateral / posteromedial
The rotary arc on the Triathlon insert provides surgeons with the
potential to fine tune: -ANSWER-Tibial rotation for preferred tray
coverage on the proximal tibia
The normal human femur bows: -ANSWER-Anteriorly
What do the letters K-S-S stand for? -ANSWER-Knee Society Score
In a retrospective study, the FlexRod has been shown to allow more ".
" of a femoral component than a rigid rod. -ANSWER-Downsizing
In a prospective study, patients whose procedure included the use of
the FlexRod had: -ANSWER-Greater range of motion and higher Knee
Society Scores than patients who had their procedure done with a
straight rod.
Images from Stryker's SOMA database demonstrate that
accommodating for a patient's femoral bow can reduce the potential
for femoral component ". " in bone types with an anterior femoral bow.
-ANSWER-Overhang
Which of the following is not a potential consequence of kinematic
conflict (the knee components not being aligned properly and moving
in harmony with each other): -ANSWER-Increased Patellofemoral
function
Based on fit studies, the Triathlon knee developed ". " optimal femoral
/ tibial sizes -ANSWER-8
