Patella resurfacing during primary total knee arthroplasty (TKA) remains controversial. Variation in published results for patella resurfacing may potentially be explained by differences in design between TKA brands. We interrogated NJR-PROMs data to ascertain whether there is an early functional benefit to resurfacing the patella, both overall and for each of the five most popular primary knee designs through use of the Oxford Knee Score. A total of 8103 resurfaced TKAs and 15,290 nonresurfaced TKAs were studied. There was a large variation in the proportion of knees undergoing patella resurfacing by brand (Nexgen=16% versus Triathlon=52%). Patellar resurfacing did not significantly influence the magnitude of improvement in overall knee function or anterior knee-specific function irrespective of TKA brand or for cruciate retaining versus sacrificing designs.
在初次全膝关节置换术（TKA）中进行髌骨表面置换仍然存在争议。髌骨表面置换的发表结果存在差异，这可能是由于 TKA 品牌之间的设计差异造成的。我们查阅了 NJR-PROMs 数据，以确定使用牛津膝关节评分（Oxford Knee Score）是否在髌骨表面置换方面具有早期的功能优势，包括总体上和五种最流行的初次膝关节设计中的每一种。共研究了 8103 例髌骨表面置换 TKA 和 15290 例非髌骨表面置换 TKA。不同品牌的膝关节髌骨表面置换比例差异很大（Nexgen=16%，Triathlon=52%）。无论 TKA 品牌如何，或者是保留交叉韧带还是牺牲交叉韧带的设计，髌骨表面置换都不会显著影响整体膝关节功能或前膝关节特异性功能的改善程度。
