The major problem of total knee arthroplasty for the degenerative knee is blood loss after the operation. This retrospective study aimed to survey the clinical outcomes especially blood loss after total knee arthroplasty in Buddhachinaraj Phitsanulok hospital, from January 2010 to March 2018. Fifty osteoarthritic patients who had total knee arthroplasty were enrolled. They had received tranexamic acid 250 mg. plus normal saline 50 mL. soak intra-operation within 10 minutes period. The amounts of blood loss after operation in all the patients were recorded by vacuum drainage volume until the drainage were removed. The number of patients who required blood replacement, length of stay in hospital and the complications were also recorded. The descriptive statistics were analyzed by percentage, mean, standard deviation and range. The results showed that, the post-operative blood loss in the drainage was average 613 +/- 262.06 mL. Only one patient required blood transfusion. The hospital length of stay was average 7 days (7.290+/-6.23 days) and there was no complication found. In conclusion, the total knee arthroplasty with intra-operative soak with tranexamic acid can reduce blood loss and safe for patients
