This multicenter clinical trial aims to investigate the exact effect of drainage use for osteoarthritis patients in total knee arthroplasty (TKA) on post-operative performance.
This is a multicenter,open-label randomized controlled trail. A total of 100 participants will receive same perioperative treatment schedule, and all surgeries will be carried out by the same surgeon. Among all the participants, 50 patients will be randomly assigned to the experiment group in which a drainage will be applied during the surgery, while another 50 patients will be randomly assigned to the control group without a drainage application in the surgery.Data on perioperative bleeding volume, swelling of lower extremities, pain score will be collected and analysed.

Applying a drain tube during TKA procedure
No drain tube will be applied during TKA procedure
The change of bleeding volume in perioperative period
The difference between baseline Hct collected before operation and Hct collected one week after operation
Time frame: before operation and one week after operation
Swelling of the lower extremities
perimeter of lower extremities before and after operation
Time frame: one week after operation
Range of motion
Range of motion of the knee received operation
Time frame: one week after operation
Pain
Use the Visual Analogue Scale to estimate the pain and its score ranges from 0 to 10. The higher the score is, the more severe pain the patient is feeling.
Time frame: one week after operation
