Patella resurfacing with TKA may be more cost-effective vs patellar retention

Resurfacing the patella in primary total knee arthroplasty may be more cost-effective compared with patellar retention, with higher costs resulting from a higher revision rate for secondary resurfacing in patients who did not undergo patella resurfacing, according to a cost-effectiveness analysis published in The Journal of Arthroplasty. Using data from the 2014 Australian Registry, researchers used a decision analytic model to conduct a cost-effectiveness analysis representing a hypothetical TKA cohort with or without patellar resurfacing. Researchers used the quality-adjusted life-year
