Application of Iced Normal Saline Combined With Cocktail Perfusion in Total Knee Arthroplasty

Patients with confirmed primary knee osteoarthritis in stage IV by preoperative X-ray were included in present study, whilst subsequent arthritis (including rheumatoid arthritis, Gouty arthritis, traumatic arthritis, etc.) were excluded. After assessment, sixty qualified patients who voluntarily participating in this study have understood the research project were included in the present study and the corresponding consent forms were signed. Patients were randomly classified into three groups with different interventions, each group contains 20 patients. Group A: twenty patients who were given intraoperative joint cavity infusion therapy using 20ml tranexamic and 40ml iced normal saline; Group B twenty patients who were given 20ml of iced normal saline, 20ml of iced cocktail and 20ml of tranexamic; the left twenty patients were given joint cavity infusion therapy with 20ml tranexamic only as the control group. All the study personnel including the patients, their family members, the nursing staff and the leading operator were blind to the treatment allocation.
