Abstract
PURPOSE: To determine whether intra-articular tranexamic acid (TXA) use after total knee arthroplasty (TKA) results in decreased postoperative blood transfusion and length of hospital stay. METHODS: Medical records of 1981 patients (mean age, 69.2 years) who underwent primary TKA with (n=1006) or without (n=975) TXA use by any of 4 knee arthroplasty surgeons were reviewed. TXA (3000 mg/30ml) was administered via an epidural catheter into the knee joint after wound closure. Postoperative blood transfusion was given to patients with haemoglobin (Hb) level <80 g/dl on days 1 and 2 or with symptoms of acute anaemia. RESULTS: Intra-articular TXA use after TKA resulted in a lower blood transfusion rate (4.5% [45/1006] vs. 14.8% [144/975], p<0.0001), fewer units of blood transfused (86 vs. 313 units, p<0.0001), fewer units of blood transfused per 100 patients (8.5 vs. 32.1, p<0.0001), and shorter length of hospital stay (4.7±2.3 vs. 5.3±2.7 days, p<0.0001). Total cost savings with respect to the reduction in blood transfusion was AU$143.68 per patient. When the change in length of hospital stay and TXA costs were included, the overall saving was AU$631.36 per patient. CONCLUSION: Intra-articular TXA use can reduce costs as a result of decreased blood transfusion rate and length of hospital stay in patients undergoing TKA.
