Abstract

Knee arthroplasty is a major surgery with potential significant blood loss. Assess the efficacy and safety of topical administration of 3g of tranexamic acid (TXA) in terms of reducing blood loss in knee arthroplasty. A randomized, phase III, double-blind, placebo-controlled clinical trial has been conducted. We included 150 patients in 2 parallel treatment groups (75 per arm). The solution was administered topically intra-articular after cementation and prior to capsular closure. Analytical determinations were made before and after surgery to quantify blood loss. Total blood loss for the placebo group was 831.5ml and 662.3ml for the TXA group. The difference between the 2 groups was 169.2ml; which means a save of 20.4%; this difference being statistically significant (p The administration of TXA topically after cementation of the prosthetic components in total knee arthroplasty in a single dose has demonstrated being safe and effective.
