ARTHROPLASTY IOT FINAL EXAM 2026 100%
PASS ASSURED EXAMINATION SOLUTIONS
what is it and what are the most common uses?
- correct answer- reconstruction or
replacement of a joint to relieve pain,
improve or maintain ROM, and correct
deformity. The most common uses of
arthroplasty are for patients with OA, RA,
avascular necrosis, congenital deformities or
dislocations, and other systemic problems.
what are three different types? - correct
answer- including surgical reshaping of the
bones of the joints, replacement of part of a
joint (hemiarthroplasty), and total joint
replacement
replacement arthoplasty is available for what?
- correct answer- elbows, shoulders,
phalangeal joints of the fingers, wrists,
hips, knees, ankles, and feet.
what can a THA be used for? - correct answer-
OA, RA, and other conditions. Partial and

total hip replacements are also used to treat
hip fractures.
how is a THA done? - correct answer-
prosthesis (implant) replaces the ball and
socket joint and upper shaft of the femur
what is the difference between cemented and
non cemented THA? - correct answer- The socket
can be "cemented" in place with polymethyl
methacrylate, which bonds to the bone. The
socket may also be inserted and not cemented
("cementless"). Cementless THAs may provide
longer-term prosthesis stability by
facilitating biologic ingrowth of new bone
tissue into the porous surface coating of the
prosthesis.
who is cementless usually done on? like what
age group? - correct answer- Although some
surgeons use cementless devices for all
patients, they are most often recommended for
younger, more active patients and patients
with good bone quality where bone ingrowth
into the components can be readily achieved.

what is hip resurfacing? - correct answer- An
alternative to hip replacement is hip
resurfacing, which allows the femoral head to
be preserved and reshaped rather than
replaced. (In contrast, in a THA the
prosthesis replaces the femoral head.)
-resurfaced femoral head (ball) is then capped
by a metal prosthesis
hip resurfacing is perferable in what age
groups? - correct answer- Hip resurfacing is a
more favorable option for younger, active
patients.
how long do you have to wait after resurfacing
to start physical activity again? - correct
answer- there is generally a 6-month waiting
period before strenuous activity until strong
muscles are built around the joint
Patients receiving a smaller femoral head have
a higher rate of what? as compared to what? -
correct answer- Patients receiving a smaller
femoral head (including many women) have a
higher failure rate with a resurfaced implant
when compared with patients receiving a THA
