Patellar resurfacing in total knee replacement: 20-year clinical and economic results of a large multicentre, randomised controlled trial in the UK

This study aimed to evaluate the long-term clinical and economic outcomes of patellar resurfacing during total knee replacement (TKR) over a 20-year period. The findings indicated no significant difference in the primary outcome measure, the Oxford Knee Score, between resurfaced and non-resurfaced groups; however, the resurfaced group demonstrated significantly higher quality-adjusted life-years (QALYs) and a high probability of being cost-effective. Overall, the evidence suggests that patellar resurfacing may be the preferred approach in TKR despite the lack of significant differences in some clinical endpoints.
