The effect of topical tranexamic acid on blood loss following TKA or THA .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Topical administration of tranexamic acid in primary total hip and total knee arthroplasty
J Arthroplasty. 2014 May;29(5):889-94100 patients (50 TKA and 50 THA) who were over the age of 18 and scheduled to receive either TKA or THA, were randomly assigned into 1 of 2 groups (an intervention and a placebo) to determine the effect that topical tranexamic acid, applied at the joint space immediately prior to joint closure for TKA and THA, had on blood loss in patients following surgery. The results of the study demonstrated that tranexamic acid lead to significantly higher postoperative hemoglobin level when compared to placebo treatment. A numerical improvement in the amount of blood transfused was indicated in patients who received treatment with topical tranexamic acid, but the amount did not differ significantly from those in the comparison group. No significant increase in complications was noted in patients who received tranexamic intervention.
