Efficacy and Systemic Absorption of Peri-articular Versus Intra-articular Administration of Tranexamic Acid in Total Knee Arthroplasty: A Prospective Randomized Controlled Trial.

ABSTRACT:

Background

Tranexamic acid (TXA) is widely accepted as an effective method for reducing blood loss after total knee arthroplasty (TKA). As different routes of local TXA administration have been proposed to minimize systemic complications, we aimed to investigate the effectiveness and systemic absorption of peri-articular (PA) and intra-articular (IA) administration of TXA after primary TKA.

Methods

In a randomized controlled trial of patients scheduled for unilateral primary TKA, 108 were assigned to receive PA-TXA (15 mg/kg), IA-TXA (2 g), or no TXA injection. We assessed total blood loss, blood transfusion rate, and hemoglobin level changes 48 hours after surgery. Postoperative serum TXA levels, complications, and clinical symptoms of venous thromboembolism events were als
