Abstract:

BACKGROUND: More and more patients are undergoing unicompartmental knee arthroplasty. Tranexamic acid has been injected into the articular cavity in unicompartmental knee arthroplasty in the past, and effects of intravenous combined with topical administration of tranexamic acid in unicompartmental knee arthroplasty have not been studied.

OBJECTIVE: To investigate the hemostatic effect and safety of intravenous combined with topical administration of tranexamic acid in unicompartmental knee arthroplasty.

METHODS: A retrospective analysis was conducted on the medical records of 48 patients with knee

osteoarthritis who underwent primary unilateral unicompartmental knee arthroplasty in the First Department of Orthopedics of Zhongshan People’s Hospital from June 2015 to December 2019. The patients were divided into two groups according to perioperative use of tranexamic acid. The 30 patients in the experimental group received intravenous infusion of 1.0 g tranexamic acid before surgery and 0.5 g tranexamic acid mixed with cocktail before closing the incision. The 18 patients in the control group did not receive tranexamic acid before surgery or cocktail with tranexamic acid before closing the incision. The dominant, hidden and total blood loss of the two groups, the loss of hemoglobin and hematocrit on day 2 after the operation, the number of blood transfusion cases, the duration of postoperative and total hospital stay, and any complications within 30 days after the operation were compared and analyzed.

RESULTS AND CONCLUSION: (1) The dominant, hidden and total blood loss, and the loss of hemoglobin and hematocrit were significantly less in the experimental group than in the control group on day 2 after surgery, with statistically significant differences (P < 0.05). (2) There was no statistically significant difference between the two groups in the number of blood transfusions, postoperative and total hospital stay and any complications within 30 days after surgery (P > 0.05). (3) The results confirmed that the intravenous combined with topical administration of tranexamic acid in the unicompartmental knee arthroplasty has obvious hemostatic effect, and has a certain safety.
