JR 201 EXAM PREP QUESTIONS
AND ANSWERS 2026 - 2027
when depressed, the black button on the faceplate of the Triathlon
Standard A/P sizing guide allows the surgeon to set the rotation
holes for 0 to 6 degrees of external rotation for either a left or
right knee
true
when depressed, the black rotation adjustment button on the
faceplate of the Triathlon MIS A/P sizing guide allows the surgeon
to set the rotation holes for 0-6 degrees of external rotation for
either a left or right knee
true
unlike the Triathlon Standard A/P sizer stylus which is only used
to determine the runout of a femoral implant on the anterior
femoral surface (a bladerunner is used independently to measure
the A/P dimension), the Triathlon MIS stylus is used to not only
determine the runout, but also to measure the A/P dimension of a
femoral implant
true
the Triathlon MIS A/P sizing guide can be used in open or
minimally invasive total knee procedures. regardless of whether
the procedure is open or minimally invasive, the tip of the MIS
sizing guide measuring stylus should approach the apex point of
the lateral femoral condyle from the medial side of the faceplate
of the A/P sizing guide
true
,Triathlon femoral components size #1-#7 grow in the sagittal
plane approximately 3mm per size anteriorly from the position of
the lugs on the implant. the posterior distance from the position of
the lugs on the implant remains the same throughout the #1-#7
sizing matrix. in the event of an "in-between" measurement of,
for instance, size #4 1/2 instead of size #4, the 1/2 would represent
an appropriate additional amount of a 1 1/2 mm (1.5mm) of A/P
bone dimension on the flex distal femur
true
the Triathlon MIS A/P sizing guide has an adjustment housing
feature that allows a surgeon user to either raise or lower the
position of the "EPI" holes 1.5mm anterior or posterior. based on
the image provided, if a surgeon wanted to lower the position of
the "EPI" holes 1.5mm he/she would use the hex wrench shown to
rotate the adjustment housing mechanism (A/P translation
adjustment) towards the "upsize" position on the instrument
true
the Triathlon MIS A/P sizing guide allows the operating surgeon
to adjust for "in-between" size measurements by allowing the
surgeon to raise or lower the position of the "EPI" holes by
1.5mm. the Triathlon Standard A/P sizing guide cannot be
adjusted to accommodate "in-between" size measurements
true
the Triathlon Standard modular 4:1 femoral cutting block can be
used with a strike plate. aside from providing a centered target
for the surgeon to aim the surgical mallet, the strike plate protects
the chamfer cutting slots on the 4:1 cutting block from being
damaged as the surgeon drives the cutting block onto the distal
femur
true
,instead of using an independent strike plate, the Triathlon MIS
modular 4:1 femoral cutting block is driven onto the distal femur
by utilizing the MIS femoral cutting block impactor/extractor
which has a built-in strike plate
true
a bladerunner can be utilized to pre-check the levels of the bone
cuts through the cutting slots of the Triathlon Standard and
Triathlon MIS 4:1 femoral cutting blocks
true
the recommended cutting sequence for the Triathlon Standard
and Triathlon MIS femoral cutting blocks is: anterior condyles,
posterior condyles, posterior chamfer, anterior chamfer
true
upon the completion of the femoral bone cuts with either the
Triathlon Standard of Triathlon MIS 4:1 cutting block the planes
of the anterior femoral resection and the posterior condylar
resection should be parallel to the transepicondylar axis of the
knee and perpendicular to the mechanical axis
true
if the operating surgeon wants to attach a trial femoral implant to
a positioning instrument, he/she can use either the Triathlon
Standard femoral impactor/extractor or the Triathlon MIS trial
femoral extractor. in the image provided, the instrument marked
"A" is the Triathlon Standard femoral impactor. "B" is the MIS
trial instrument
true
if the operating surgeon wants to impact a trial/femoral implant
without attaching the trial/femoral implant to the driving
instrument, they can either use the Triathlon Standard femoral
, impactor or the Triathlon MIS femoral trial flexion impactor. in
the image provided, the instrument marked "A" is the Triathlon
MIS femoral flexion impactor. "B" is the Triathlon Standard
femoral impactor
true
Triathlon Standard femoral impactor/ extractor can be attached
to a slap hammer to remove the CR or PS femoral trial from the
femur. by using the slap hammer to remove the femoral trial,
excessive stress on the bone could be reduced, especially when
removing a PS femoral trial
true
the Triathlon knee instrumentation has a curved osteotome that
the operating surgeon can use to remove osteophytes from behind
the femoral condyles. the curved osteotome can be used to remove
osteophytes behind the femoral condyles with either the PS box
cutting guide, or a femoral trial placed on the cut surfaces of the
distal femur
true
Triathlon Standard & Triathlon MIS instrumentation includes a
1/4" drill w/ stop to prepare the distal surface of the cut femur to
receive the lugs (pegs) of a Triathlon CR femoral component. the
same 1/4" drill bit is used to prepare holes in the PS box cutting
guide for the optional modular lugs (pegs) that can be assembled
onto a Triathlon cemented PS femoral component
true
a special slip torque driver is utilized to attach optional modular
pegs to a Triathlon Cemented P/S femoral component
true
