PURPOSE OF THE STUDY Patellar surface replacement during total knee arthroplasty is still a matter of discussion among orthopedic surgeons. The purpose of this study was to examine possible benefits of patellar surface replacement in selected @entity1 with symptomatic @entity85 . We have not found any studies in the literature that compare the results of patella management solely for valgus or varus @entity85 nor those that compare both. MATERIAL AND METHODS @entity1 were randomly assigned to a group that would receive patellar surface replacement during total knee arthroplasty and a group of @entity1 in whom total knee arthroplasty was performed without patellar surface replacement. 60 @entity1 were included in the study. Total knee arthroplasty with patellar resurfacing (TKAPR) was performed in 30, and without PR (TKA) in 30 of them. Results were prospectively gathered and compared at regular intervals. RESULTS There were no significant differences between groups for examined parameters except for Oxford Knee Score at 6 months which was in favor of patellar resurfacing group. DISCUSSION The decision whether to replace the patella or not is currently exclusively a matter of surgeon's choice. Establishing selection criteria for @entity1 that would benefit from patella resurfacing could, therefore, be very useful for both @entity1 and orthopaedic surgeons performing total knee replacement. CONCLUSIONS Although evidence in our study could not strongly suggest performing patella resurfacing in @entity1 with @entity85 , the results were slightly better in the patella resurfacing group and this trend could increase if larger series of @entity1 would be employed. A longer follow-up period would be required for clear-cut decisions and more prospective studies are warranted. Key words: knee, arthroplasty, patella, replacement, valgus, @entity85 .
