摘要

Aim. The need to resurface or not the patella during total knee arthroplasty is still an open problem. Some surgeons always recommend to replace the patella, others suggest to not replace routinely the patella and others to replace it only in selected cases. The purpose of this study was to compare clinical results of knee prosthesis with or without patella replacement in a series of 30 patients treated for bilateral knee arthritis using a medial pivot prosthesis (Advance Wright, Arlington TN).
Methods. Between January 2003 and October 2004 in our Hospital a consecutive series of 30 patients were treated for bilateral knee arthritis. All patients underwent a bilateral total knee replacement with a mean interval of 152 days between the two procedures. All patients were randomized to resurface or not the patella during the first procedure and to receive the opposite treatment during the second intervention.
Results. At a mean follow-up of 4.1 years no complications occurred in the treated knees. We did not observe statistically significant differences in the Functional Score, Knee Score and patient's satisfaction.
Conclusions. On the basis of our experience we believe that patella resurfacing should not he performed routinely when Advance prostheses are used.
