In the article entitled “Racial and Ethnic Disparities in Utilization Rate, Hospital Volume, and Perioperative Outcomes After Total Knee Arthroplasty” (J Bone Joint Surg Am. 2016;98:1243-52), by Zhang et al., there were errors in Tables I and II, on pages 1245, 1246, and 1248. In both tables, frequencies with a count of ≤10 were reported in individual table cells, which is against the rules put forth by the Healthcare Cost and Utilization Project. Any cell that had contained a specific value that was ≤10 should have contained “≤10.”
