Erratum to: Clin Orthop Relat Res DOI 10.1007/s11999-009-1217-8

It has been brought to our attention by one of the online readers that there is an error in the Abstract and Results sections of our manuscript. We meant to say that the decrease in hemoglobin was less in 2008 than in 2007—as shown by the data in Table 2 and hence indicating, as the Discussion correctly points out, that the TEA protocol seems to reduce the perioperative decrease in hemoglobin when compared with a similar cohort of patients who did not receive TEA.

The first sentence in the Results section of the Abstract currently states: We found a reduction in the decrease in hemoglobin in 2007 compared with 2008 for THA and TKA (46 to 39 g/L and 45 to 36 g/L, respectively), which led to a reduction in transfusion rates (13.5% to 3.6% and 13.1% to 2.0%, respectively and higher hemoglobin levels at discharge.

The first sentence in the Results section of the Abstract should be: We found a reduction in the decrease in hemoglobin in 2008 compared with 2007 for THA and TKA (39 from 46 g/L and 36 from 45 g/L, respectively), which led to a reduction in transfusion rates (3.6% from 13.5% and 2.0% from 13.4%, respectively) and higher hemoglobin levels at discharge.

The first sentence in the Results section of the manuscript currently states: The decrease in hemoglobin was less in 2007 than in 2008 for patients who had THAs and TKAs (46 to 39 g/L [p < 0.001] and 45 to 36 g/L [p < 0.001] respectively) (Table 2).

The first sentence in the Results section of the manuscript should be: The decrease in hemoglobin was less in 2008 than in 2007 for patients who had THAs and TKAs (39 from 46 g/L [p < 0.001] and 36 from 45 g/L [p < 0.001], respectively) (Table 2).

We apologize for this error.
