JR 201 HIP COMPREHENSIVE STUDY GUIDE
2026 FULL QUESTIONS AND SOLUTIONS
GRADED A+
◍ T/F: The clinical transepicondylar axis is perpendicular to the mechanical
axis in the knee.
Answer: True
◍ T/F: the trident II acetabular cup menu is comprised of three implant designs
for cementless use only. Each cup design will have an outside diameter that
will be smaller than the labeled diameter on the packaging..
Answer: False- will be larger
◍ t/F: when the polyethylene liner is in its final prelocked position it can be
impacted into the acetabular cup. an appropriately sized insert impactor tip
is loaded onto the insert positoner/impactor handle. when the impactor
handle is aligned with the axis of the cup liner then can be driven into the
cup to lock its position.
Answer: true
◍ t/F: trident alumina inserts are compatible with Trident II acetabular cups.
Answer: false
◍ the triathlon MIS A/P sizing guide can be used in open or minimally
invasive total knee procedures. t/F: regardless of the procedure being open
or minimally invasive, the tip of the MIS sizing guide measuring stylus
should approach the apex point of the medial femoral condyle from the
lateral side of the faceplate on the A/P sizing guide.
Answer: False- apex point of the lateral femoral condyle from the medial
side of the faceplate
◍ the triathlon universal tibial trial template can be fixed to the surface of the
, tibia. t/f: the handle of the keel punch guide can be locked onto the universal
tibial trial.
Answer: true
◍ t/F: when implanting a triathlon TS tibial insert, the reinforcement bar
prepackaged with the Triathlon TS polyethylene implant must always be
driven into the round hole on top of the insert's polyethylene post.
Answer: true
◍ when utilizied appropriately, the Flex rod can assist the operating surgeon in
positioning (when needed) the Triathlon standard or triathlon MIS distal
femoral cutting assembly in a more flexed position than a rigid rod. t/f: in
the sagittal view illustration provided; the triathlon flexrod is in a less flexed
position than the straight rod in the image.
Answer: false- more flexed position
◍ t/f: 6.5mm low profile hex screws can be used with: trident II clusterhole
(hemispherical), Trident II PSL clusterhole HA, and trident II tritanium
(clusterhole and Multihole) implants. the screw size range is 15mm to
60mm (5mm increments per size). the average angulation potential of a
trident II low profile hex screw is 37 degrees.
Answer: true
◍ t/F: a surgeon has the option of cementing a triathlon tritanium baseplate
should he/she decided that the host bone stock is not suitable for cementless
fixation.
Answer: true
◍ t/f: triathlon tritanium baseplate tibial peg drill templates are not
size-specific.
Answer: false
◍ t/F: in the triathlon standard/ MIS cemented knee instrumentation. there are
two different sized keel punch guides and three different sized keel punches.
the size #1,2,3. the size #4,5,6,7 and 8 keel punch guide work with one of
two punches; one labeled #4,5 and 6 and other labeled #7-8.
