Abstract
BACKGROUND Tranexamic acid (TXA) is regarded as one of the most important drugs in reducing blood loss and hemoglobin (Hb) drop after total knee arthroplasty (TKA) or total hip arthroplasty (THA). Treatment with tranexamic acid (TXA) by intravenous application has been discussed extensively. Recently, several studies have reported that oral administration has an effect on blood sparing. Therefore, we performed a meta-analysis to investigate the efficacy and safety between oral TXA and intravenous TXA (IV-TXA) for blood sparing in total knee and hip arthroplasty. METHODS Randomized controlled trials (RCTs) or retrospective cohort studies (RCSs) about relevant research were searched for by using PubMed (1996-April 2017), Embase (1980-April 2017), and the Cochrane Library (CENTRAL, April 2017). Five studies that compared oral with IV administration of TXA were included in our meta-analysis. Meta-analysis results were collected and analyzed by the software Review Manager 5.3 (Copenhagen: The Nordic Cochrane Center, The Collaboration, 2014). RESULTS Five studies containing 3474 patients met the inclusion criteria. Our pooled data analysis indicated that oral TXA was as effective as the IV-TXA in terms of the average Hb drop (P = 0.88), total Hb loss (P = 0.57), total blood loss (P = 0.42), transfusion rate (P = 0.16), complications (P = 0.61), and length of hospital stay (P = 1.00). CONCLUSIONS Compared with the IV-TXA method, oral TXA shows similar blood-sparing efficacy for preventing hemoglobin drop, total hemoglobin loss, and total blood loss following TKA or THA. In addition, no significant differences of transfusion rate, complications, or length of hospital stay were found between the 2 groups. However, because of the limited number of included studies, more studies of high quality are needed to further identify the optimal administration time for oral TXA.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is gradually regarded as an effective choice for end-stage osteoarthritis or rheumatic arthritis. In the past, the management of tranexamic acid (TXA) using intravenous injection or topical application has been extensively researched. However, several studies have reported that oral TXA has an effect on blood loss. Therefore, a meta-analysis should be performed to determine whether oral TXA helps to prevent blood loss. METHODS Randomized controlled trials or retrospective cohort studies about relevant studies were searched in PubMed (1996-April 2017), Embase (1980-April 2017), and the Cochrane Library (CENTRAL, April 2017). Six studies that compared oral TXA to non-TXA were included in our meta-analysis. Meta-analyses (PRISMA) guidelines, the Cochrane Handbook, and the Jadad scale were used to evaluate the included studies and the results to ensure that the meta-analysis was viable. RESULTS In accordance with inclusion and exclusion, six studies with 2553 patients (oral TXA = 1386, without TXA = 1167) were eligible and accepted into this meta-analysis. Pooled data indicated that the oral TXA group was effective compared to the without TXA group in terms of hemoglobin (Hb) drop (P < 0.05), blood loss at 24 h (P < 0.05), total blood loss (P < 0.05), and the transfusion rate (P < 0.05). No significant differences were found in the length of hospital stay (P = 0.96) and complications (P = 0.39). CONCLUSION Compared to the non-TXA group, the oral TXA group showed effects of blood sparing. Considering the cost and effectiveness, oral TXA is useful for TKA.

Abstract
The objective of this systematic review and meta-analysis was to evaluate the efficacy and safety of i.v. tranexamic acid (TXA) in simultaneous bilateral total knee arthroplasty (TKA). Potentially relevant published reports were identified from the following electronic databases: Medline, PubMed, Embase, ScienceDirect and Cochrane Library. RevMan v5.3was used to pool data. Two randomized controlled trials and four case-control studies met the inclusion criteria. The current meta-analysis identified significant differences between TXA group and control groups in terms of postoperative hemoglobin concentration (P < 0.01), drainage volume (P < 0.01), transfusion rate (P < 0.01) and units transfused (P = 0.006). There were no significant differences in length of stay (P = 0.66), operation time (P = 0.81) or and incidence of adverse effects such as infection (P = 0.42), deep venous thrombosis (DVT) (P = 0.88) and pulmonary embolism (PE) (P = 0.11). Our results show that i.v. administration of TXA in simultaneous bilateral TKA reduces postoperative drops in hemoglobin concentration, drainage volume, and transfusion requirements and does not prolong length of stay or operation time. Moreover, no adverse effects, such as infection, DVT or PE, were associated with TXA.

Abstract
OBJECTIVE A systematic review of randomized controlled trials (RCTs) and non-RCTs was performed to evaluate efficacy for the reduction of postoperative blood loss and transfusion requirements of topical use of tranexamic acid in patients undergoing primary total hip arthroplasty. METHOD Potential articles were identified from Medline (1966 - September 2014), Embase (1980 - September 2014), Pubmed (1980 - September 2014) and The Cochrane Central Register of Controlled Trials. Other internet databases are also searched to find trials according to the Cochrane Collaboration guidelines. Moreover, gray literatures are also selected from the reference list of the included studies. High quality randomized controlled trials (RCTs) and non-RCTs were selected. The software RevMan 5.1 was used for the mate-analysis. RESULTS Four RCTs and four non-RCT meet the inclusion criteria. There were significant differences in hemoglobin, total blood loss, transfusion requirements and postoperative drainage volume between TXA groups and control groups. There were no significant differences in length of stay, incidence of wound infection, deep vein thrombosis (DVT) and pulmonary embolism (PE) between treatment and control groups. CONCLUSIONS Present meta-analysis indicates that the antifibrinolytic agent, also known as tranexamic acid, could reduce hemoglobin decline, volume of drainage, total blood loss and transfusion requirements after THA, and is not related to adverse reactions or complications such as wound infection, DVT and PE.Copyright 2015 Surgical Associates Ltd.
