Abstract

Background: Total knee arthroplasty (TKA) is gradually regarded as an effective choice for end-stage osteoarthritis or rheumatic arthritis. In the past, the management of tranexamic acid (TXA) using intravenous injection or topical application has been extensively researched. However, several studies have reported that oral TXA has an effect on blood loss. Therefore, a meta-analysis should be performed to determine whether oral TXA helps to prevent blood loss.

Methods: Randomized controlled trials or retrospective cohort studies about relevant studies were searched in PubMed (1996-April 2017), Embase (1980-April 2017), and the Cochrane Library (CENTRAL, April 2017). Six studies that compared oral TXA to non-TXA were included in our meta-analysis. Meta-analyses (PRISMA) guidelines, the Cochrane Handbook, and the Jadad scale were used to evaluate the included studies and the results to ensure that the meta-analysis was viable.

Results: In accordance with inclusion and exclusion, six studies with 2553 patients (oral TXA = 1386, without TXA = 1167) were eligible and accepted into this meta-analysis. Pooled data indicated that the oral TXA group was effective compared to the without TXA group in terms of hemoglobin (Hb) drop (P < 0.05), blood loss at 24 h (P < 0.05), total blood loss (P < 0.05), and the transfusion rate (P < 0.05). No significant differences were found in the length of hospital stay (P = 0.96) and complications (P = 0.39).

Conclusion: Compared to the non-TXA group, the oral TXA group showed effects of blood sparing. Considering the cost and effectiveness, oral TXA is useful for TKA.
