Background: Previous studies often focus on the comparison between the entire tourniquet technology and halfway tourniquet technology which used the tourniquet when the bone cement combined with the prosthesis. Objective: To research the influence of clinical symptoms and limb function on postoperative patients between the entire process of tourniquet and tourniquet released electric coagulation and bone wax hemostatic method before the incision is closed, both combined with autologous blood transfusion in total knee arthroplasty. Methods: Sixty cases of knee osteoarthritis patients who underwent total knee arthroplasty were selected for research. Thirty cases were treated with entire process of tourniquet (tourniquet group) and 30 cases were treated with relax tourniquet before wound closing, and hemostasis using electric coagulation and bone wax respectively (electric coagulation group). After the total knee arthroplasty, the autologous blood transfusion devices were placed in the patients of two groups. The early clinical effect and affected limb function of patients in two groups were evaluated by comparing the amount of bleeding and draining, the American knee society knee score of clinical symptoms and function postoperatively. Results and Conclusion: The intraoperative blood loss of tourniquet group (50±10) mL was lower than that of electric coagulation group (180±120) mL (P < 0.05); the drainage flow of tourniquet group (237±83) mL was lower than that of electric coagulation group (285±215) mL (P < 0.05). There was no significant difference of early American knee society knee score, and the difference of joint hematoma occurring rate and lower extremity venous thrombosis incidence was not significant. In total knee arthroplasty, the intraoperative bleeding and postoperative drainage volume of the hemostatic method before closing the incision is more than that of the entire process of tourniquet, and there is no significant difference of the early postoperative clinical symptoms and limb function.
