Abstract Background The use and the optimal timing of tourniquet during primary total knee arthroplasty (TKA) is controversial. Most previous studies failed to show clinically significant differences in different strategies. The aim of this study was to determine how three strategies of tourniquet application affect the outcome in TKA patients. Methods This was a prospective randomized controlled study. Patients who undergo TKA were randomized into one of the three groups (1:1:1 ratio): tourniquet inflated from skin incision to cement hardening, tourniquet from cement application to hardening, and tourniquet from skin incision to skin closure. The perioperative blood loss, limb swelling, and complications were recorded. The level of hemoglobin, hematocrit, C-reactive protein (CRP), interleukin (IL)-6, creatine kinase (CK), and lactate dehydrogenase (LDH) were determined. Patients' thigh and TKA wound pain, Knee Society knee score (KSKS) and Knee Society functional assessment (KSFA) scores, and rehabilitation parameters were evaluated. Results A total of 90 patients were enrolled. The baseline characteristics were comparable. We only found significant difference in the intraoperative blood loss (skin to cement: 58.7 ± 36.1 mL, cement-only: 147.8 ± 107.9 mL, skin to skin: 16.3 ± 13.1 mL, p < 0.0001). There were no statistical differences in postoperative drainage, thigh/knee circumference, change of hemoglobin/hematocrit, CRP, IL-6, CK, and LDH on day 1 to day 4 after surgery. The thigh/TKA wound Visual Analogue Scale scores, KSKS score, KSFA score, and rehabilitation parameters were not significantly different at up to 6-month follow-up. No thromboembolic events were noted. Conclusion Our results revealed that there was no best tourniquet strategy in TKA. Different tourniquet methods can be utilized based on surgeon preference without affecting outcomes.
