Tranexamic Acid in a Multimodal Blood Loss Prevention Protocol to Decrease Blood Loss in Revision Total Knee...

Area of Science:

• Orthopedic Surgery
• Anesthesiology
• Hematology

Background:

• Revision knee surgery is associated with significant blood loss and high transfusion rates.
• Minimizing perioperative blood loss is crucial for patient safety and recovery.

Purpose of the Study:

• To evaluate the efficacy of a multimodal blood loss management approach, including tranexamic acid (TXA), in reducing blood loss and transfusion requirements during revision knee surgery.

Main Methods:

• A retrospective study compared 44 knees treated with TXA and a multimodal protocol to 43 control knees.
• Only revisions using a single implant system were included to ensure homogeneity.
• Patient groups were comparable in terms of surgical complexity and case severity.

Main Results:

• The transfusion rate decreased significantly from 58% in the control group to 5% in the TXA-treated group.
• Postoperative hemoglobin drop was significantly lower in the TXA group.
• TXA use was the primary factor reducing transfusion risk (OR=15), while longer surgical time increased it (OR=1.15).

Conclusions:

• A multimodal approach incorporating two-dose intravenous TXA is effective in revision knee replacement.
• This strategy significantly reduces transfusion rates, postoperative blood loss, and hemoglobin drop.
• The findings support the routine use of TXA in multimodal protocols for revision knee surgery.
