THE INFLUENCE OF PATELLA RESURFACING ON PATIENT-REPORTED OUTCOMES – A RETROSPECTIVE OBSERVATIONAL STUDY AFTER TOTAL KNEE REPLACEMENT
Abstract:
Patella resurfacing in total knee replacement remains a controversial topic, in spite of the
multitude of studies published in the literature. We comparatively evaluated the outcomes of total knee
arthroplasty with unresurfaced/ resurfaced patellae in a consecutive series of 155 patients, at 1 year
postoperatively: 86 (55.5%) with resurfaced patellae and 69 (44.5%) unresurfaced. The two patient
groups were similar in terms of age, gender, diagnosis, osteoarthritis grade, involved knee and
alignment, and type of endoprosthesis implanted. We found no significant difference in Knee Society
Score and anterior knee pain; the only observed difference was in tourniquet time, which was longer in
the resurfaced group (p< 0.0001). Patients with unresurfaced and resurfaced patella show similar
results in terms of knee function and anterior knee pain at 1 year postoperatively, with no significant
differences. Further long term studies are needed to clearly show the superiority of one procedure over
the other.
