Global Trends in Patellar Resurfacing From 2004 to 2022

International rates of patellar resurfacing in primary total knee arthroplasty (TKA) are highly variable. This study sought to determine how trends in patellar resurfacing rates have changed between 2004 and 2022. In addition, we investigated how modern rates of revision have varied between resurfaced and un-resurfaced patellae in primary TKA among national joint registries.
