Can tranexamic acid change preoperative anemia management during total joint arthroplasty?

Figure 2 Hemoglobin levels in total knee arthroplasty using tranexamic acid. Boxplots showing median and interquartile ranges for hemoglobin levels in each group on each hospital day are shown. Both groups experienced a fall in hemoglobin following; in this case the nonanemic patients had a significant greater fall then the anemic patients at the first postoperative day (but still had a higher median hemoglobin). None of the patients in either group required transfusion. TKA: Total knee arthroplasty.
