Tranexamic Acid (TA) has been shown to reduce transfusion rates in Total Knee Replacement (TKR) without complication. In our unit it was added to our routine enhanced recovery protocol. No other changes were made to the protocol at this time and as such we sought to examine the effects of TA on wound complication and transfusion rate. All patients undergoing primary TKR over a 12 month period were identified. Notes and online records were reviewed to collate demographics, length of stay, use of TA, thromboprophylaxis, blood transfusion, wound complications and haemoglobin levels. All patients received a Columbus navigated TKR with a tourniquet. Only patients who received 14 days of Dalteparin for thromboprophylaxis were included. 124 patients were included, 72 receiving TA and 52 not. Mean age was 70. Four patients required a blood transfusion all of whom did not receive TA (p = 0.029). Mean change in Hb was 22 without TA and 21 with (p = 0.859). Mean length of stay was 6.83 days without Tranexamic Acid and 5.15 with (p < 0.001). 15% of patients (n=11) of the TA group had a wound complication, with 40% of patients (n=21) in the non TA group (p = 0.003). There was one ultrasound confirmed DVT (non TA group). No patients were diagnosed with pulmonary embolus. In our unit we have demonstrated a significantly lower transfusion rate, wound complication rate and length of stay, without any significant increase in thromboembolic disease with the use of TA in TKR.
Orthopedic surgery is one of the most blood-consuming surgeries. Currently there has been a radical change in transfusion policies, developing a series of therapeutic measures essentially created to minimize the use of allogeneic blood. On the one hand, the safety of our patients must be even more our main objective. On the other hand, our economic resources are more restricted and therefore we must evaluate our surgical techniques and proceedings in order to be safer and more cost-effective. The aim of this study is to report our results of the blood lost, the percentage of blood loss, the necessity of transfussions and how many blood pakages are needed. From a sample of 2400 total knee arthroplasties proceedings, we analyze some surgical proceedings such as lligament balance, patelar traking, artrotomy, ischemia, femoro-tibial axis and type of arthroplasty. We also examine the total blood lost and the percentage of total blood loss after 4 hours, after 24hours and after 48 hour of the total
Introduction. Patellofemoral complications remain a very common post-operative problem in association with total
