摘要

Objective: To study the influence of patellar resurfacing on quality of life under a standardised score. The chosen score was the Knee Society Score (KSS), which considers range of motion, pain, contractors, alignment and stability. Methods: Retrospective review of 60 patients submitted to total knee arthroplasty (TKA) was divided into two groups: with patellar resurfacing (PR) and without patellar resurfacing (NPR). We reviewed data from these patients containing the KSS, which are routinely used in our service. Data were analysed from 2013 to 2014, with a minimal patient follow-up of 18 months. Results: There were no unsatisfactory scores in our study. Total scores (KSS) were similar between the groups (mean KSS: PR = 88.36 ± 9.64;NPR = 84.26 ± 9.44 [p = 0.1]). While stratifying into groups (poor, fair, good, excellent), we found excellent results in 84.8% of PR versus 59.3% NPR (p = 0.056). These data did not reach statistical significance and can therefore be considered a coincidental result. Conclusion: Although these results did not show statistical significance (p = 0.056), patellar resurfacing patients tend to get more “excellent” results after 18 months of follow-up in quality of life when evaluated by KSS. Perhaps a larger amount of patients would suffice to acquire statistical significance in a future study.
