Arthrex Final DEX Exam Questions and Answers Latest
QUESTION 1
Which of the following instruments is primarily used in arthroscopic labral repair procedures?
A. Rongeur
B. Arthroscopic suture passer
C. Oscillating saw
D. Bone tamp
CORRECT ANSWER: B
RATIONALE: An arthroscopic suture passer is specifically designed to pass sutures through soft
tissues like the labrum during arthroscopic repairs. A rongeur is used for bone trimming, an
oscillating saw for osteotomies, and a bone tamp for impaction or fracture management.
QUESTION 2
True or False: Arthrex TightRope® technology allows for adjustable fixation in ligament
reconstruction.
CORRECT ANSWER: True
RATIONALE: Arthrex TightRope® systems utilize adjustable suture loops that enable controlled
tensioning during ligament reconstruction, offering flexibility and secure fixation.
QUESTION 3
In rotator cuff repair, which suture configuration most effectively distributes load across the
tendon-bone interface?
A. Simple stitch
B. Mason-Allen stitch
C. Rip-stop stitch
D. Double-row construct
CORRECT ANSWER: D
RATIONALE: Double-row constructs recreate the natural footprint of the tendon, maximizing
load distribution and minimizing gap formation compared to single-stitch or single-row
methods.
,QUESTION 4
What is the primary purpose of fluid management systems in arthroscopy?
A. Heating the joint
B. Enhancing visualization
C. Delivering anesthesia
D. Removing bone debris only
CORRECT ANSWER: B
RATIONALE: Fluid management maintains pressure and clears debris, providing clear
visualization during arthroscopy. It does not function to heat, anesthetize, or singularly remove
debris.
QUESTION 5
During ACL reconstruction with a hamstring autograft, what is the typical diameter range of the
femoral tunnel?
A. 4–6 mm
B. 6–8 mm
C. 8–10 mm
D. 10–12 mm
CORRECT ANSWER: C
RATIONALE: Hamstring autograft diameters usually fall within 8–10 mm, matching the femoral
tunnel size for optimal fit and graft integrity.
QUESTION 6
In shoulder arthroscopy, the “50-yard line” refers to what anatomical landmark?
A. The midpoint of the glenohumeral joint
B. The rotator cuff insertion
C. The acromioclavicular joint
D. The biceps groove
CORRECT ANSWER: A
RATIONALE: The “50-yard line” is a colloquial term used by surgeons to refer to the midline of
the glenohumeral joint—an important reference for orientation in arthroscopy.
,QUESTION 7
Short Answer:
Identify one potential complication from over-tensioning a graft during ligament reconstruction.
CORRECT ANSWER: Graft over-constraining leading to joint stiffness
RATIONALE: Over-tensioning can result in excessive joint constraint, limited range of motion, and
premature graft failure due to abnormal biomechanics.
QUESTION 8
In which anatomical location is the Arthrex BioComposite interference screw most commonly
used?
A. Tibial tunnel fixation
B. Glenoid labrum anchoring
C. Acromioclavicular joint stabilization
D. Achilles tendon repair
CORRECT ANSWER: A
RATIONALE: BioComposite interference screws are most frequently employed in securing grafts
within tibial tunnels during ACL or PCL reconstructions.
QUESTION 9
True or False: The PushLock® anchor system enables knotless fixation in soft tissue-to-bone
repairs.
CORRECT ANSWER: True
RATIONALE: The PushLock® system employs a mechanism that captures suture tails within the
eyelet, allowing for knotless and secure soft tissue fixation to bone.
QUESTION 10
Which type of suture is typically preferred for high tensile strength and minimal elongation in
orthopedic repairs?
A. Nylon
B. Polyester braided
, C. Catgut
D. Silk
CORRECT ANSWER: B
RATIONALE: Polyester braided sutures (such as FiberWire®) provide excellent tensile strength,
minimal elongation, and superior knot security, making them ideal for orthopedic use.
QUESTION 11
Which of the following describes the functional role of the SwiveLock® anchor in soft-tissue
fixation?
A. Delivers intra-articular fluid
B. Provides screw-like knotless fixation
C. Measures graft tension
D. Acts as a tendon harvester
CORRECT ANSWER: B
RATIONALE: SwiveLock® anchors feature a screw-in design that provides knotless fixation of soft
tissue to bone, simplifying procedures and reducing suture bulk.
QUESTION 12
When preparing a femoral tunnel for ACL reconstruction, the guide pin is typically aimed at
which clock position (right knee view)?
A. 10 o’clock
B. 11 o’clock
C. 12 o’clock
D. 9 o’clock
CORRECT ANSWER: B
RATIONALE: For a right knee, the femoral tunnel is placed around the 11 o’clock position (1
o’clock on a left knee) to recreate the anatomical ACL footprint.
QUESTION 13
In an Achilles tendon repair using the PARS system, what is a key advantage compared to
traditional open repair?
A. Increased infection rate
B. Smaller incision and decreased wound complications
QUESTION 1
