The nurse instructs the patient who is to have a unicompartmental knee replacement that a major advantage of this partial knee replacement is that:
a. the patient will be up and walking 2 to 3 hours after the operation.
b. the kneecap is completely removed.
c. the procedure is especially helpful in the treatment of rheumatoid arthritis.
d. a small titanium disk replaces the worn cartilage.
ANS: A
Unicompartmental knee arthroplasty is also referred to as partial knee replacement in which the worn cartilage is replaced with a plastic disk. It is not as invasive as a full knee replacement and does not disturb the kneecap so that the patient can be up and walking in 2 to 3 hours after surgery. It is not recommended for RA patients.
