Abstract
Objective. This study addresses functional data, pain, and the reop-
eration rate in patients undergoing primary total knee arthroplasty
(TKA) during which the patella was or was not replaced. Methods:
Fifty-three knees were included, 18 with the patella replaced and
35 with the patella not replaced. WOMAC and SF-12 scores and
knee pain were analyzed preoperatively and 3, 6, and 12 months
after TKA. The reoperation rate was also evaluated. Results: Both
groups presented significant improvement in WOMAC score and
pain at all postoperative follow-up appointments. There was no
significant difference between the groups in all evaluated variables.
Two subjects in the group did not undergo patellar replacement due
to complaints of anterior knee pain after arthroplasty. There was no
difference between the groups in relation to the reoperation rate.
Conclusion: Patients receiving patellar replacement during TKA did
exhibit significant differences in the rate of reoperation, function, or
pain when compared to patients in which the patella was replaced.
