Cavanaugh A, Rauh MJ, Thompson CA, et al. - Via a prospective study of 102,767 Women’s Health Initiative postmenopausal women initially aged 50-79, examining utilization rates of primary total knee arthroplasty (TKA) between non-Hispanic Black/African American, non-Hispanic White, and Hispanic/Latina women, researchers assessed racial and ethnic disparities in utilization of TKA in relation to demographic, health, and socioeconomic status variables. TKA utilization was greater among White vs Black and Hispanic women. Black and Hispanic women were significantly less prone to undergo TKA following adjusting for age, among women with health indicators for TKA including diagnosis of arthritis, moderate to severe joint pain, and mobility disability. Adjustment for socioeconomic status (SES) modestly attenuated the measured disparity, but important variations persisted. In comparison with White women, Black and Hispanic women were significantly less inclined to undergo TKA following considering requirement and appropriateness for TKA and SES.
