Abstract:

Background

The aim of this study was to evaluate financial benefits of intra-articular tranexamic acid [TXA] in total knee arthroplasty [TKA].

Methods

We analyzed retrospective data for 1981 patients who underwent primary TKA with intra-articular injection of TXA in to the knee joint following wound closure.

Results

The number of patients receiving transfusion decreased from 14.7% to 4.5% with TXA use (p-value <0.0001). The number of units transfused per 100 patients decreased from 32.1 units to 8.5 units with TXA use [p-value <0.0001]. Mean length of stay decreased by 0.6 days, from 5.3 (SD 2.7) days to 4.7 [SD 2.3] days (p < 0.0001]). Overall, there was total health care cost saving of $631.35 per patient.

Conclusion

Use of intra-articular TXA significantly decreased the number of patients who were transfused, number of blood transfusions and length of stay which brought about an overall decrease in health care costs.
