Abstract:

Objective: To investigate the influence of different tranexamic acid regimens on patients with severe knee osteoarthritis after total knee arthroplasty(TKA). Methods: A retrospective analysis was conducted on the medical records of patients who underwent unilateral TKA for the first time at the Department of Orthopedics, Panzhihua Central Hospital, from January 2019 to November 2021. According to different postoperative tranexamic acid regimens, the patients were divided into a control group (intravenous infusion of 1 g tranexamic acid at 3 and 6 hours after surgery) and an experimental group (intravenous infusion of 1 g tranexamic acid at 3, 6 hours, 1, and 2 days after surgery). The postoperative laboratory indicators, total perioperative blood loss and blood transfusion, occurrence of deep venous thrombosis of lower limbs, postoperative pain, knee joint swelling, and knee joint function were compared between the two groups. Results: The total perioperative blood loss, perioperative blood transfusion rate, resting pain score and knee swelling degree of the experimental group were significantly lower than those of the control group, while the knee function score of the experiment group was significantly higher than that of the control group, with statistical significance (P<0.05). Conclusion: Prolonged use of tranexamic acid after TKA can further reduce blood loss, alleviate inflammatory response, reduce pain and swelling in the surgical area, and promote rapid recovery in patients, which is worthy of clinical promotion.
