Disparities in Outcomes for African Americans and Whites Undergoing Total Knee Arthroplasty: A Systematic Literature Review.

African Americans in the United States undergo total knee arthroplasty (TKA) less often than whites, in part because of lower expectations among African Americans for successful surgery. Whether this lower expectation is justified is unknown. Our objective is to compare health-related quality of life (HRQOL) and satisfaction after TKA between African Americans and whites.
