Fibrin sealant (FS) comprises a mixture of fibrinogen and thrombin that controls bleeding, reduces blood transfusions, improves tissue healing and shortens postoperative recovery time after various surgical procedures. However, no single study has been large enough to definitively determine whether fibrin sealant is safe and effective. We report a meta-analysis of randomized controlled trials (RCTs) evaluating the efficacy and safety of fibrin sealant in total knee arthroplasty.
Articles published before August, 2012 were identified from PubMed, Embase, The Cochrane Library and other internet databases. Relevant journals and the recommendations of expert panels were also searched manually. We included only high-quality RCTs. Two independent reviewers searched and assessed the literature. Relevant data were analysed using RevMan 5.0.
Seven RCTs met the inclusion criteria. Use of fibrin sealant significantly reduced haemoglobin decline mean difference (MD = -0.72), 95 % confidence interval [95 % CI (-0.83, -0.62), p < 0.00001], postoperative drainage volume [MD = -354.53, 95 % CI (-482.43, -226.63), p < 0.00001], the proportion of patients requiring blood transfusion risk differences [RD = -0.27, 95 % CI (-0.45, -0.08), p = 0.006] and the incidence of wound haematoma [RD = -0.11, 95 % CI (-0.22, -0.00), p = 0.04]. There were no significant differences in deep vein thrombosis, pulmonary embolism, infection rate or other complications between groups.
Use of fibrin sealant in total knee arthroplasty was effective and safe, reduced haemoglobin decline, postoperative drainage volume, incidence of haematoma and need for blood transfusion, and did not increase the risk of complications. Due to the limited quality of the evidence currently available, more high-quality RCTs are required. LEVEL OF EVIDENCE: II.

    ABSTRACT: Fibrin sealant (FS) and tranexamic acid (TXA) have been used in total knee arthroplasty (TKA) to minimize perioperative blood loss. The efficacy of FS has been debated, and few studies have looked into the effects of FS and TXA on perioperative coagulability. The current study retrospectively reviewed 100 cases of unilateral primary TKA. Twenty-five cases served as blank controls, FS was used without TXA in 23, TXA was used without FS in 20, and both FS and TXA (FS + TXA) were used in 32. FS was sprayed before wound closure whereas 1 g of TXA was intravenously administered before incision and 1 g was administered 15 min before tourniquet release. Hematocrit and hemoglobin levels and thromboelastography (TEG) parameters were assessed pre-operatively and on day 1, 4, and 9 post-operatively. Blood transfusions were noted and the incidence of symptomatic DVT/PE was determined. Hematocrit and hemoglobin levels were significantly higher in the TXA and FS + TXA groups compared to the control and FS groups on day 1, 4, and 9 post-operatively. Hematocrit and hemoglobin levels in the control group were similar to those in the FS group and hematocrit and hemoglobin levels in the TXA group were similar to those in the FS + TXA group. TEG parameters (R, K, α, MA, and CI) remained within normal ranges. Mean CI was less than +3 in all four groups, suggesting that hypercoagulation was not promoted. One patient in the FS group received an allogeneic transfusion. Incidence of symptomatic DVT/PE was not noted. Intravenous TXA significantly reduced perioperative blood loss in patients undergoing a TKA but FS did not. Administration of FS in addition to TXA was not superior to TXA alone. FS and/or TXA did not increase the risk of hypercoagulation according to TEG parameters. Intravenous administration of 1 g of TXA pre-operatively and administration of 1 g before tourniquet release is an effective and safe method of reducing blood loss in TKA.

    ABSTRACT: Topical application of tranexamic acid to the knee joint before closure in total knee arthroplasty reduces postoperative bleeding without increase in complication. However, it is unknown the effectiveness of topic TXA performed with other topical medications, like povidone-iodine solution. One hundred and twenty-five patients were randomized to receive 100mL of povidone-iodine solution (control: group A) or 1.5 (group B) and 3.0g (group C) of topical TXA in povidone-iodine solution applied into the knee before closure in total knee arthroplasty. The patients in the TXA groups had higher mean postoperative hemoglobin levels (P=0.01 and P=0.03 in groups B and C, respectively) and a reduced postoperative blood loss in the TXA groups (P=0.07 and P=0.09 in groups B and C, respectively). No significant complications were observed. In this study, topical application of tranexamic acid after total knee arthroplasty together with povidone-iodine solution results in higher postoperative hemoglobin levels and lower blood loss compared with those in the control group without other complications.
