Assessment
Primary outcomes
pain at tourniquet infration is evaluated with a Visual Analogue Scale from 0 to 10 on postoperative day 1.
Key secondary outcomes
pain at the tourniquet infration on postoperative day 2 and 2 weeks,and wound pain on postoperative day 1, 2, and 2 weeks using the VAS.
Leg swelling is evaluated by femoral and lower leg circumference on preoperative and postoperative day 1.
Postoperative complications.
Joint range of motion at 2 and 6 weeks postoperatively.
Clinical scores at preoperative and 6 weeks postoperative are evaluated by questionnaire(knee injury and osteoarthritis score).
Intraoperative and postoperative blood loss evaluated by blood sampling data.
