Abstract:
Objective To evaluate the application value of tranexamic acid in total knee arthroplasty. Methods 120 elderly patients with knee osteoarthritis admitted to Department of Joint Surgery in our hospital from December 2018 to March 2020 were selected as study subjects. They were divided into the control group and the observation group by random number table method, with 60 patients in each group. The control group was treated with total knee arthroplasty. The observation group received one tranexamic acid injection during and after total knee arthroplasty. Both groups were followed up for 6 months after the operation. The operation-related indexes in two groups, preoperative and postoperative coagulation function 48 h after operation, preoperative and postoperative knee joint function 6 months after operation were compared. The incidence of complications during hospitalization in the two groups was counted. Results The intraoperative blood loss, hidden blood loss and postoperative drainage volume of the observation group were lower than those in the control group (P<0.05). The postoperative drainage time, drying time and wound healing time in the observation group were all shorter than those in the control group (P<0.05). There was no significant difference in prothrombin time (PT), partial thromboplastin time (APTT) and whole blood fibrinogen (FIB) between two groups before the surgery and 48 h after operation (P>0.05). No statistically significant difference was observed between the two groups (P>0.05). Compared with those before operation, the pain, walking stability, walking distance, walking assistance, flexor extension and muscle strength scores of the subjects in the two groups increased 6 months after the operation. The index scores in the observation group were higher than those in the control group (P<0.05). During the treatment, the total complication rate was 8.33% in the observation group and 13.33% in the control group, with no statistically significant difference between the two groups (P>0.05). Conclusion Tranexamic acid can effectively reduce blood loss, postoperative drainage volume, and postoperative drainage time in total knee arthroplasty for elderly patients with knee osteoarthritis. It promotes wound healing, improves knee joint function, and has little effect on coagulation function and less postoperative complications.
