A new topical hemostatic agent TT-173 reduces blood loss in a sheep model of total knee arthroplasty. Knee 2017; 24:1454-1461. [PMID: 28865948 DOI: 10.1016/j.knee.2017.08.055] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2017] [Revised: 08/02/2017] [Accepted: 08/22/2017] [Indexed: 02/02/2023]
Abstract
BACKGROUND Total knee arthroplasty is associated with blood loss during the intervention and may require allogenic blood transfusion. Treatments such as tranexamic acid and fibrin sealants improved the bleeding control in several clinical trials, but the hemorrhage associated with the intervention is still significant. Thus far, very few studies have evaluated hemostatic treatments in animal models of total knee arthroplasty. This work describes a sheep model of bleeding associated with total knee arthroplasty and investigates a new class of hemostatic treatment based on recombinant tissue factor. METHODS Sheep were treated with the anticoagulant heparin, and the joint was accessed by a paramedial incision. Ligaments and menisci were eliminated and femoral condyles and tibia plateau were sectioned exposing the trabecular bone. An intra-articular drain was used to recover and quantify the blood loss during the 90-min period after treatment. The efficacy of one milligram and three milligrams of TT-173 was evaluated and compared with tranexamic acid. The occurrence of analytical alterations and systemic absorption was also investigated. RESULTS Treatment with TT-173 reduced the blood loss in comparison with control or tranexamic acid. No significant differences were observed between the two doses evaluated. Moreover, a dose of six milligrams of TT-173 did not induce any clinical or analytical alteration, and significant systemic absorption was not observed. CONCLUSION Data obtained strongly suggest that TT-173 could be useful in reducing the blood loss associated with total knee arthroplasty and without safety concerns derived from the systemic absorption of the product.
