Patellar resurfacing in knee arthroplasty: A comprehensive review and meta-analysis

Table 1 Revision rates associated with different patellar resurfacing approaches, (%)¹

Ref.	Routine resurfacing	Selective resurfacing	Non-resurfacing
Smith et al[2] (2015)	4.2	4.8	6.5
Khan et al[19] (2016)	3.5	4.0	5.8
Delanois et al[15] (2017)	5.1	5.5	7.3
Yi et al[5] (2015)	4.8	5.2	6.9
Li et al[20] (2019)	3.9	4.4	6.1

¹The table shows that across all five studies, routine resurfacing consistently has the lowest revision rates compared to selective resurfacing and non-resurfacing. Selective resurfacing generally has a moderate revision rate, while non-resurfacing shows the highest revision rates in all studies. These findings suggest that routine patellar resurfacing may lead to better long-term outcomes in terms of fewer revision surgeries needed, compared to selective or non-resurfacing strategies.
