Abstract

Background: Patients undergoing cementless total knee arthroplasty (TKA) sometimes suffer large blood loss. In a retrospective study, we explored whether postoperative intra-articular retrograde injection of tranexamic acid (TA) and leaving a drain clamp in place for 1 h reduced blood loss.Patients and methods: Patients (n = 140) treated with unilateral primary cementless TKA (posterior cruciate ligament retained) were divided into two groups: those who had an intra-articular injection of TA (1000 mg) and drain clamping for 1 h postoperatively (study group, n = 70) and those who were not given TA and did not undergo clamping of their drains (control group, n = 70). Postoperative total blood loss, volume of drainage, hemoglobin level, transfusion amounts and rates, D-dimer level at postoperative day (POD) 7, and complications were recorded.Results: Total blood loss, total drainage, mean transfusion volume, and transfusion rates were lower in the study group than in controls (P < 0.001). Hemoglobin levels on PODs 1 and 14 were similar in the groups, but on POD 7 the hemoglobin level was higher in the study group than in controls (P < 0.001). D-dimer level on POD 7 was lower in the study group than in controls (P < 0.05). There were no complications in either group.Conclusions: Immediately postoperative intra-articular retrograde injection of TA and 1 h of drain-clamping effectively reduced blood loss and blood transfusion after cementless TKA. We believe that this method is simple, easy, and suitable for these patients. © 2012 Mutsuzaki and Ikeda; licensee BioMed Central Ltd.
