The use of tranexamic acid (TXA) during primary total knee arthroplasty (TKA) is well documented. However, considering the potential side effects, including deep vein thrombosis (DVT) and pulmonary embolism (PE), the ideal route of administration remains controversial. Therefore, we performed a meta-analysis to compare the efficacy of topical versus intravenous TXA and explore the most effective regimen in patients undergoing primary TKA. ⋯ Topical TXA had a similar efficacy to intravenous TXA in reducing blood transfusion and blood loss, and did not increase the risk of thromboembolic complications in primary TKA. Besides, the current meta-analysis suggested that three times of intravenous TXA is efficient and safe. We also recommended 2 g topical TXA instead of 1 g topical TXA because it was more efficient to reduce blood transfusion rate and total blood loss and did not increase thromboembolic complications.

Meta Analysis Comparative Study
Continuous Local Infiltration Analgesia after TKA: A Meta-Analysis.
The analgesic effect of local infiltration analgesia (LIA) after total knee arthroplasty (TKA) has been reported to be less than 24 hours. The concept of continuous LIA (CLIA) has been developed to achieve prolonged analgesia by bolus injections or by pump infusion of analgesics. The purpose of this meta-analysis is to assess the effect of CLIA versus single-shot injection LIA (SLIA) and placebo on pain after TKA. ⋯ CLIA can possibly provide a reduced pain perception for 24 hours postoperative at rest after performing a TKA. This effect may persist until 48 hours postoperative during activity. Due to the high level of heterogeneity no firm further conclusions can be drawn.
